You can put this solution on YOUR website! In a certain college, 33% of the physics majors belong to ethnic minorities. If 8 students are selected at random from the physics majors, what is the probability that more than 5 belong to an ethnic minority?
--------
Binomial Problem with n = 8 and p(minority) = 0.33
----
P(6<= x <=8) = 1 - binomcdf(8,0.33,5) = 1 - 0.98134 = 0.01866
