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

### Answer & Explanation

Willie

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)
$=\frac{n\left(sophomore\right)+n\left(male\right)-n\left(sophomoreandmale\right)}{n\left(S\right)}$
$=\frac{15+18-8}{33}$
$=\frac{25}{33}$
Thus, the probability that a randomly selected student is a sophomore or male is $\frac{25}{33}$.
