): a study conducted at a certain college shows that 55% of the school's graduates find a job in their chosen field within a year after graduation. Find the probability that among 7 randomly selected graduates, at least one finds a job in his or her chosen field within a year of graduating
--------
Binomial Problem with n = 7 and p(find job) = 0.55
-------
P(at least one) = 1 - P(none of 7) = 1- (0.45)^7 = 0.9963
