A supercomputer is shared by 600 independent subscribers. Each day, each subscriber uses the facility with probability 0.301. The number of tasks sent by each active user has Geometric distribution with parameter 0.15, and each task takes a Gamma(10, 3) distributed computer time (in minutes). Tasks are processed consecutively. (ANSWER TO THIS QUESTION IS NOT REQUIRED TO BE HANDWRITTEN a) What is the probability that all the tasks will be processed, that is, the total requested computer time is less than 60 hours?
