Question
An experiment can result in one of five equally likely simple events ,
E1, E2, , E5.
Events A, B, and C are defined as follows.A: E1, E5 | P(A) | = | 0.4 |
|
|||
B: E2, E3, E4, E5 | P(B) | = | 0.8 |
|
|||
C: E1, E2 | P(C) | = | 0.4 |
Refer to the following probabilities.
P(A ∩ B) | = | 0.2 |
P(A|B) | = | 0.25 |
P(B|A) | = | 0.5 |
P(B ∪ C) | = | 1 |
P(B|C) | = | 0.5 |
P(C|B) | = | 0.25 |
Use the Addition and Multiplication Rules to find the following probabilities.
(a)
P(A ∪ B)
P(A ∪ B)
= + − = (b)
P(A ∩ B)
P(A ∩ B) = · P(B)
= (c)
P(B ∩ C)
P(B ∩ C) = · P(C)
= Do the results agree with those obtained by listing the simple events in each?
P(A ∪ B) = P({E1, E2, E3, E4, E5}) | = | 1 |
P(A ∩ B) = P({E5}) | = | 0.2 |
P(B ∩ C) = P({E2}) | = | 0.2 |
YesNo
An experiment can result in one or both of the events A and B, with the probabilities shown below. Use the probability table to answer this question.
A | AC | |
---|---|---|
B | 0.37 | 0.41 |
BC | 0.15 | 0.07 |
Refer to the following probabilities.
P(A) | = | 0.52 |
P(B) | = | 0.78 |
P(A ∩ B) | = | 0.37 |
P(A ∪ B) | = | 0.93 |
P(A|B) | = | 0.474 |
P(B|A) | = | 0.712 |
Are events A and B independent? Explain.
Since , A and B independent.
