An examination consisting of ten true-or-false questions was taken by a class of 100 students. The probability distribution of the random variable X, where X denotes the number of questions answered correctly by a randomly chosen student, is represented by the accompanying histogram. Assuming the rectangle with base centered on the number 8 is the only rectangle missing, what should be the height of this rectangle? .25 .20 .15 .10 .05 + 3 5 8 9 10
