Respuesta :

The probability that the selected student is a sophomore given that he is a boy will be 5/12.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events.

we need to select the probability that the selected student is a sophomore given that he is a boy;

In this case;

P(B) = P(boy)

P(A) = P(sophomore)

The total number of students which is 12 + 18 = 30

From the table;

P(B) = 12/30

P(A n B) = 5/30

So;

P(A|B) = 5/30 / 12/30

= 5/30 x 30/12 = 5/12

Hence, the probability that the selected student is a sophomore given that he is a boy will be 5/12.
