The probability that a randomly selected student is a sophomore or male is,

P(sophomore or male)=P(sophomore)+P(male)-P(sophomore and male)

$=\frac{n(sophomore)+n(male)-n(sophomoreandmale)}{n(S)}$

$=\frac{15+18-8}{33}$

$=\frac{25}{33}$

Thus, the probability that a randomly selected student is a sophomore or male is$\frac{25}{33}$ .

P(sophomore or male)=P(sophomore)+P(male)-P(sophomore and male)

Thus, the probability that a randomly selected student is a sophomore or male is
