Question

1 and In an experiment, the probability that event A occurs is –, the probability that event B occurs is 5 1 the probability that events A and B both occur is What is the probability that A occurs given that B occurs? Simplify any fractions. Submit

Answer 1

Solution

We have the following info given:

P(A) = 4/5

P(B)= 1/7

P(A and B) = 1/9

We want to find this probability:

P(A|B)= P(A and B)/P(B)

Replacing we got:

$P(A|B)=\frac{\frac{1}{9}}{\frac{1}{7}}=\frac{7}{9}$
