At a school carnival, the probability of winning \(\text{both}~\text{parts}\) of a \(\text{two}\text{-}\text{step}~\text{challenge}\) on \(\text{one}~\text{try}\) is \(0.18\). If \(75~\text{students}\) \(\text{each}~\text{try}\) the challenge \(\text{once}\), about how many students would you expect to win \(\text{both}~\text{parts}\)?
