The probability that at least one graduate finds a job is 1 minus the probability that none of the graduates find a job. The probability that a single graduate does not find a job is 0.38 (1 - 0.62). For 5 graduates, the probability that none find a job is 0.38^5. Thus, the probability that at least one finds a job is 1 - 0.38^5 = 0.992.
