Question

Events A and B are independent. find the missing probability

P(A)= 1/4 , P(B)= 3/5, P(B I A) =?

Answer 1

hello : P(A and B) = 3/20

Explanation:

events A and B are independent:

P(A and B) = P(A)×P(B)

P(A and B) = (1/4)×(3/5)

P(A and B) =3/20

continu ....

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