A study conducted at a certain college shows that 55% of the school's graduates find a job in their 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.
-----
P(at least one) = 1 - P(none of the seven find a job)
----
= 1 - (0.45)^7
= 1 - 0.0037
= 0.963
