Answer :
Given info
P(A) = 0.40
P(B) = 0.30
P(A and B) = 0.15
What we want to find: P(A|B)
Use the conditional probability formula
P(A|B) = P(A and B)/P(B)
P(A|B) = 0.15/0.30
P(A|B) = 0.50
Answer: 0.50
P(A) = 0.40
P(B) = 0.30
P(A and B) = 0.15
What we want to find: P(A|B)
Use the conditional probability formula

P(A|B) = 0.15/0.30
P(A|B) = 0.50
Answer: 0.50
