Ten percent of all electrical batteries are defective. In a random selection of 8 of these batteries, find the probability that (a) There are no defective batteries. (b) More than 15 percent of the batteries are defective. (c) Between 8 and 12 percent of the batteries are defective. Suppose there was a random selection of n = 50 batteries in Prob. 2. Determine approximate probabilities for parts (a), (b), and (c) of that problem.
