The probability that a randomly selected graduate finds a job in their chosen field within a year of graduating is 0.62. The probability that a randomly selected graduate does not find a job in their chosen field within a year of graduating is 1 - 0.62 = 0.38. The probability that none of the 7 randomly selected graduates finds a job in their chosen field within a year of graduating is 0.38^7 = 0.001. The probability that at least one of the 7 randomly selected graduates finds a job in their chosen field within a year of graduating is 1 - 0.001 = 0.999.
