Simulate the chance experiment described in the previous exercise using five slips of paper, with two marked defective and three marked not defective.

Place the slips in a box, mix them well, and draw out two. Record the number of defective boards. Replace the slips and repeat until you have 50 observations of the value x. Construct a relative frequency distribution for the 50 observations, and compare this with the probability distribution obtained in the previous exercise.
