Answer:

The answer to your problem is, B, 0.5

Explanation:

We are given the following table below;

X Y Z Total

A 32 10 28 70

B 6 5 25 36

C 18 15 7 40

Total 56 30 60 146

As we know that the conditional probability formula of P(A/B) is given by:

P(A/B) =
(P(AnB))/(P(b))

P(C/Y) =
(P(CnY))/(P(Y))

P ( Y ) =
(30)/(146) and P(CnY) =
(15)/(146) [ because of the third column shown ]

Thus, the answer is, B. 0.5
