Find P(Y|B) from the information in the table.

To the nearest tenth, what is the value of P(Y|B)?

A.) 0.2

B.) 0.3

C.) 0.4

D.) 0.5

Answer 1

P( Y/B) = P( YΠ B)/P(B)

P( YΠB) = 34

P(B) = 85

P( YΠB)/P(B) = 34/85 = 0.4

C) option

Answer 2

Probability is the ratio of the favorable event to the total number of events. The probability of P(Y|B) is 0.4. Then the correct option is C.

What is probability?

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.

The probability is given by

$\rm Probability = \dfrac{Favorable \ events}{Total \ number \ of \ event}$

The probability of P(T|B) will be

Favorable event = 34

Total events = 85

Then

$P(Y|B) = \dfrac{34}{85}\\\\P(Y|B) = 0.4$

The probability of P(Y|B) is 0.4.

Thus, the correct option is C.
