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