Question 867248: In a class of 30 students the probability of having someone absent is approximately 88%. Determine the probability that on any given day everyone is absent. Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! p(absent) = .88, n = 30
P(x = 30) = binompdf(30, .88, 30) = .0216 0r 2.16% chance of that happening
