You can put this solution on YOUR website! Say that a randomly chosen individual can identify the professor with probability 0.68. What is the probability that, of 6 chosen people, exactly 3 people recognize the professor?
-------
Binomial Problem with n = 6 ; p(ident) = 0.68
------
P(x = 3) = 6C3*0.68^3*0.37^3 = binompdf(6,0.68,3) = 0.2061
