A certain trouble shooting procedure on an engine of a car has a success rate of 75%. a) Suppose that the procedure is performed on four cars. What is the probability that the procedure is successful on exactly 2 cars? b) Suppose that the procedure is performed on six cars. What is the probability that the procedure is successful for at least 3 cars? c) Suppose that the procedure is performed on five cars. What is the probability that the procedure is unsuccessful for at least 2 cars? d) what is the mean and variance of the trouble shooting procedure if performed for six cars?
