Suppose we consider the experiment of randomly selecting 1 student as a representative from a class of 80 students. In this class there are 5 black male students, 25 black female students, 35 white male students, and 15 white female students, as indicated below.
Find:
P(B)P (W)P(M)P(F)P(B / M) = P(B and M) / P(M)P (B and M)

Suppose we consider the experiment of randomly selecting 1 student as a representative from a class of 80 students. In this class there are 5 black male students, 25 black female students, 35 white male students, and 15 white female students, as indicated below.
LetB = event that the student is black.W = event that the student is white.M = event that the student is male.F = event that the student was female.
Find:
P(B)P (W)P(M)P(F)P(B / M) = P(B and M) / P(M)P (B and M)
