In a certain college, 30% of the physics majors belong to ethnic minorities. If 10 students areselected at random from the physics majors, what is the probability that no more than 4 belong to an ethnic minority?
----
Binomial Problem with n = 10 and p(minority) = 0.30.
----
P(x<= 4) = binomcdf(10,0.3,4) = 0.8497
