A mechanical press is used to mold shapes for plastic toys. When the machine is adjusted and working well, it still produces about 8% defective toys. The toys are manufactured in lots of n = 100. Let r be a random variable representing the number of defective toys in a lot. Find the probability that between 6 and 9 defective toys are produced in a lot of n = 100 toys
