Question

5 In an experiment, the probability that event B occurs is and the probability that event A occurs given 9' 9 5 that event B occurs is - 8 What is the probability that events A and B both occur? Simplify any fractions.

Answer 1

In this problem, in order to occur event A we have to have event B so to get the probabilitie that bout of them happen we will multiply the probabilities so:

`P=(5)/(9)\cdot(5)/(8)=(25)/(72)`
