Question

SOMEONE HELP PLEASE!!!

Find P(C|Y) from the information in the table.
To the nearest tenth, what is the value of P(C|Y)?

A. 0.4

B. 0.5

C. 0.7

D. 0.8

Answer 1

The answer is B. 0.5.

Answer 2

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
