4. Suppose the probability of event A is 0.23, the probability of the intersection of event A and event Bis 0.12, and the probability of the union of event A and event B is 0.34. Find the probability of the complement of event B.
(A) 0.11
(B) 0.23
(C) 0.48
(D) 0.52
(E) 0.77

Step-by-step explanation:

Given

Required

Find P(B')

First, we calculate P(B).

We have:

Substitute values

Collect like terms

P(B') is then calculated as:

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.
