19. In a certain college, 33% of the physics majors belong to ethnic minorities. If 10students are selected at random from the physics majors, what is the probabilitythat exactly 2 belong to an ethnic minority?20. Use the information in the previous question to find the probability that at most 2students belong to a minority.

We have given that Success of probability p =33%=0.33 Number of trials n=10 X~binomial ( n ,p)
