Find P(C|Y) from the information in the table. A 5-column table has 4 rows. The first column has entries A, B, C, Total. The sec

ond column is labeled X with entries 32, 6, 18, 56. The third column is labeled Y with entries 10, 5, 15, 30. The fourth column is labeled Z with entries 28, 25, 7, 60. The fifth column is labeled Total with entries 70, 36, 40, 146. To the nearest tenth, what is the value of P(C|Y)? 0. 4 0. 5 0. 7 0. 8.

The probability is the ratio of the favorable event to the total number of events. The P(C|Y) is 0.5. Then the correct option is B.

<h3>What is probability?</h3>

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

According to the problem, the table is made

X Y Z Total

A 32 10 28 70

B 6 5 25 36

C 18 15 7 40

Total 56 30 60 146

Then the probability of will be

$\rm P(C|Y) = \dfrac{15}{30}\\\\P(C|Y) = 0.5$
