Question 1042070
Anita's reports that 45% of its customers order their food to go. If this proportion is correct, what is the probability that, in a random sample of 4 customers at Anita's, exactly 3 order their food to go? 
-------
Binomial Problem with n = 4 and p(take out) = 0.45
-----
P(x = 3) = 4C3(0.45)^3*0.55 = binompdf(4,0.45,3) = 0.2005
