Question

According to the general equation for conditional probability, if P(AD) =4/7 and P(B)= 7/8, what is P(A B)?

A.40/49
B. 16/49
C. 32/49
D. 24/49

Answer 1

It is given that
`image`

Now, the conditional probability,

`P(A|B)=(P(A \cap B))/(P(B)) =(4/7)/(7/8) =(32)/(49)`.

The correct choice is (C).
