Suppose we were told by the superintendent of schools that the probability a randomly selectedmiddle school student would have an IQ between 100 and 120 is P-0.68. If we randomly select fivestudents from the eighth grade, what is the probablity that three of them will have an lQ between1.100 and 120?
