Assume that number of accidents at the power plant follows the Poisson process with the average rate of 0.40 accidents per week. Assume all weeks are independent of each other
1) Find out the probability that there will be 5 accident-free weeks in two months (8 weeks).
2) Find out the probability that the first accident would occur during the fourth week.
3) Find out the probability that the third accident would occur during the fifth week
