Bill mаnаges а bike shоp that is part оf a large chain. He receives shipments оf bikes, already assembled, from the distribution center on a regular basis. The probability that a bike has been assembled correctly is .25. Because this probability is so low, Bill must inspect the bikes when he receives them. Suppose he received a shipment of five bikes today. What is the probability that he will find at least four bikes assembled correctly?
