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 (s o p h o m o r e) + n (m a l e) - n (s o p h o m o r e a n d m a l e)}{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}
