To the nearest tenth, what is the value of P(C|Y)? 0.4 0.5 0.7 0.8

P(C|Y) = 0.5.

Step-by-step 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

Now, we have to find the probability of P(C/Y).

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

                    P(A/B) =  

So, according to our question;

P(C/Y) =  

Here, P(Y) = and P(C Y) =    {by seeing third row and second column}

Hence, P(C/Y) =  

                       =    = 0.5.
