Question

2. (a) The time to recharge the flash is tested in three cell-phone cameras. The probability that a camera meets the recharge specification is 0.8, and the cameras perform independently. i. Find the probability that the first and second cameras pass the test and the third one fails? ii. What is the probability that the 3rd failure is obtained in five or fewer tests? (b) Changes in airport procedures require considerable planning. Arrival rates of aircraft are important factors that must be taken into account. Suppose small aircrafts arrive at a certain airport, according to a Poisson process, at the rate of 6 per hour.
