Suppose that you own an electronics store and purchase (randomly select) 15 TV sets from a production run of 500 TV sets. Of the 500 TV sets, 450 are destined to last at least five years without needing a single repair. Set up an expression using the hypergeometric distribution for the probability that at least 14 of your 15 TV sets will last at least five years without needing a single repair. Then, using the binomial tables, approximate this probability by using the binomial distribution. What justifies the approximation? Hint: p= r/N =450/500 =0.9.
