A lot of 100 fuses has 20 defective fuses. The lot is inspected by choosing 5 of the fuses at random. If all five of the fuses blow at the correct amp, the lot is accepted. Let X be the random variable equal to the number of defective fuses in the sample of five. Find the probability that at least 2 fues are defective in the sample.
