51. A new Oxbridge professor wishes to buy a house, and can afford to spend up to one million pounds. Declining the services of conventional estate agents, she consults her favourite internet property page on which houses are announced at the times of a Poisson process with intensity λ per day. House prices may be assumed to be independent random variables which are uniformly distributed over the interval (800,000, 2,000,000). She decides to view every affordable property announced during the next 30 days. The time spent viewing any given property is uniformly distributed over the range (1, 2) hours. What is the moment generating function of the total time spent viewing houses?
