A study conducted at a certain college shows that 53% of the schools graduates find a job a year after graduation. Find the probability among 7 randomly selected, at least one finds a job within a year after graduation.
-----------------------
Binomial Problem with n = 7 ; p(find job) = 0.52 ; p(don't) = 0.47
------
P(1<= x <=7)
= 1 - P(x = 0)
= 1 - 0.47^7
= 1 - 0.0051
= 0.9949
