You can put this solution on YOUR website!
If n=5 (a full week of classes) and p=0.68 (the probability that a student shows up to class), determine the theoretical mean and standard deviation for the number of classes attended.
----
mean = np = 5*0.68 = 3.4
std = sqrt(npq) = sqrt(5*0.68*0.32) = 1.0431
