Each applicant has a score. If there are a total of n applicants then each applicant whose score is above sn is accepted, where s1 = .2, s2 = .4, sn = .5,n ≥ 3. Suppose the scores of the applicants are independent uniform (0, 1)random variables and are independent of N, the number of applicants, which is Poisson distributed with mean 2. Let X denote the number of applicants that are accepted. Derive expressions for (a) P(X=0). (b) E[X].

You are a banker and are confronted with a pool of loan
applicants, each of whom can be either low risk or high risk. There
are 600 low-risk applicants and 400 highrisk applicants and each
applicant is applying for a $100 loan. A low-risk borrower will
invest the $100 loan in a project that will yield $150 with
probability 0.8 and nothing with probability 0.2 one period hence.
