If A and B are mutually exclusive events, P(A)=0.35 amd P(B)=0.45, then find (i) P(A\\’) (ii) P(B\\’)
Suppose that A and B are mutually exclusive events for which $P(A) = 0.3$ and $P(B) = 0.5$ [1]
To have mutually exclusive events means if one of those events occurs, the others cannot occur. Therefore, for the intersection of mutually exclusive events $A_\mathrm{i}$ with $\mathrm{i} \in \{1, \dots, \mathrm{n} \ | \ \mathrm{n} \in \mathbb{N} \setminus \{1\} \}$ holds $\ \bigcap_1^n A_\mathrm{i} = \emptyset$
In general, the probability of the union of two events is $P[B\bigcup C] = P[B] + P[C] – P[B\bigcap C]$ . Hence, for mutually exclusive events holds $P[\bigcup_1^n A_\mathrm{i}] = \sum\limits_1^n P[A_i]$
As already was suggested in the comments, the solutions in your textbook are not right and inappropriate for this kind of task.. Moreover, what you did in the calculation of a) was assuming $A$ and $B$ are independent and interpreting “either” as “and”
3.2 Independent and Mutually Exclusive Events – Statistics [2]
Independent and mutually exclusive do not mean the same thing.. Two events are independent if the following are true:
For example, the outcomes of two roles of a fair die are independent events. The outcome of the first roll does not change the probability for the outcome of the second roll
If two events are not independent, then we say that they are dependent events.. Sampling may be done with replacement or without replacement.
[Solved] If A and B are two mutually exclusive events, then what is t [3]

Lessons [4]
Probability is a way of summarizing the uncertainty of statements or events. It gives a numerical measure for the degree of certainty (or degree of uncertainty) of the occurrence of an event.
The enumeration of all possible outcomes is called as the sample space.. If there are totally n possible outcomes in a sample space, S and m of those are favorable for an event, A
Example:- Find the probability of getting a 3 or 5 while throwing a dice.. Answer:- Sample space, S = {1,2,3,4,5,6} and Event, A = {3,5}.

If two events, A and B, are mutually exclusive, the probability of A intersection B.. We will use the concept of probability in order to find the probability of A intersection B
Answer: The probability of A intersection B is 0 if A and B are mutually exclusive.. Let us see how we will use the concept of probability in order to find the probability of A intersection B.
The sample space A intersection B is where both co-exist at the same time.. Events A intersection B means that both events happen simultaneously
Mutually Exclusive Events [6]
Mutually exclusive events are those events that do not occur at the same time. For example, when a coin is tossed then the result will be either head or tail, but we cannot get both the results
If A and B are mutually exclusive events then its probability is given by P(A Or B) or P (A U B). Let us learn the formula of P (A U B) along with rules and examples here in this article.
In other words, mutually exclusive events are called disjoint events. If two events are considered disjoint events, then the probability of both events occurring at the same time will be zero.
SOLUTION: Events a and b are mutually exclusive. Suppose even a occurs with probability 0.14 and event b occurs with probability 0.56 A. Compute the probability that a does not occur or [7]
Suppose even a occurs with probability 0.14 and event b occurs with probability 0.56. Suppose even a occurs with probability 0.14 and event b occurs with probability 0.56
Suppose even a occurs with probability 0.14 and event b occurs with probability 0.56. Compute the probability that a does not occur or b does not occur or both
[Solved] Assume we have two events A and B that are mutually exclusive [8]
Assume we have two events A and B that are mutually exclusive. Assume we have two events, A and B, that are mutually exclusive
Suppose we have two events, A and B, with P(A) = .50 and P(B) = .60 and P(A ⋂ B) = .40. What is P(A | B)? What is P(B | A)? Are A and B independent? Why (not)?
Independent events indicate the “happening” of one event does not affect the “happening” of another. So, mutually exclusive events cannot be independent.
SOLVED: Suppose A and B are mutually exclusive events, and that P(B) = 0.44 and P(A ∪ B) = 0.81. Find P(A). [9]
Get 5 free video unlocks on our app with code GOMOBILE. Suppose A and B are mutually exclusive events, and that P(B) = 0.44 and P(A ∪ B) = 0.81
For mutually exclusive events $A$ and $B, P(A)-0.17$ and $P(B)-0.32$.a. Suppose that $A$ and $B$ be events such that $P(A)=\frac{1}{4}$ $P(B)=\frac{1}{3},$ and $P(A \text { or } B)=\frac{1}{2}.$a
In this problem, we are given that a and b these are mutually exclusive events, and we are also given the probability of b as 0.44, and we are required to determine the probability of a provided that the probability of a union b this is equal to 0.81. So here we will use this formula for probability of a union b and as we are given that a and b are exclusive events, in this case probability…
Introduction to Statistics [10]
– Determine whether two events are mutually exclusive and whether two events are independent. Independent and mutually exclusive do not mean the same thing.
– [latex]P[/latex]([latex]A[/latex]|[latex]B[/latex]) = [latex]P[/latex]([latex]A[/latex]). – [latex]P[/latex]([latex]B[/latex]|[latex]A[/latex]) = [latex]P[/latex]([latex]B[/latex])
Two events [latex]A[/latex] and [latex]B[/latex] are independent if the knowledge that one occurred does not affect the chance the other occurs. For example, the outcomes of two roles of a fair die are independent events
Q.3.76 Suppose that E and F are mutuall… [FREE SOLUTION] [11]
Suppose that E and F are mutually exclusive events of an experiment. Suppose that E and F are mutually exclusive events of an experiment
The formula for the probability of complement then P(EF)=0 gives:. Show that if independent trials of this experiment are performed, then E will occur before F with probability P(E)/[P(E) + P(F)].
This is computed by applying the formula for the sum of a geometric sequence.. The formula for the probability of complement then P(EF)=0 gives:
Mutually Exclusive Events [12]
– Turning left and turning right are Mutually Exclusive (you can’t do both at the same time). – Tossing a coin: Heads and Tails are Mutually Exclusive
– Kings and Hearts, because we can have a King of Hearts!. Let’s look at the probabilities of Mutually Exclusive events
Number of ways it can happen: 4 (there are 4 Kings). Total number of outcomes: 52 (there are 52 cards in total)
Stats: Probability Rules [13]
Two events are mutually exclusive if they cannot occur at the same time. Another word that means mutually exclusive is disjoint.
If two events are mutually exclusive, then the probability of either occurring is the sum of the probabilities of each occurring.. Given: P(A) = 0.20, P(B) = 0.70, A and B are disjoint
(Since disjoint means nothing in common, joint is what they have in common — so the values that go on the inside portion of the table are the intersections or “and”s of each pair of events). “Marginal” is another word for totals — it’s called marginal because they appear in the margins.
4.3: Independent and Mutually Exclusive Events [14]
Independent and mutually exclusive do not mean the same thing.. Two events are independent if the following are true:
For example, the outcomes of two roles of a fair die are independent events. The outcome of the first roll does not change the probability for the outcome of the second roll
If two events are NOT independent, then we say that they are dependent.. Sampling may be done with replacement or without replacement (Figure \(\PageIndex{1}\)):
Independent Events and Mutually Exclusive Events [15]
Independent event and Mutually exclusive event are a pair of probability related terms. These terms are used to describe the existence of two events in a mutually exclusive manner
Estimating probability and random variables using these terms is also not easy, and a lot depends on the definition of the independent event or mutually exclusive event. From the mathematical point of view, both these terms are used to describe several situations
The events are treated as if they are unrelated to each other. A simple event is an event that can be represented by a single point in the sample space
3.2 Independent and Mutually Exclusive Events [16]
Independent and mutually exclusive do not mean the same thing.. Two events are independent if the following are true:
For example, the outcomes of two roles of a fair die are independent events. The outcome of the first roll does not change the probability for the outcome of the second roll
If two events are NOT independent, then we say that they are dependent events.. Sampling may be done with replacement or without replacement.
