Unformatted text preview: assumed to be uniformly distributed between integer ages. Calculate the median future lifetime for (40). (37.58) 7. Mr. Ucci has only 3 hairs left on his head and he will not be growing any more. Also: (i) The future mortality of each hair follows: k  q x = 0.1( k + 1) where k = 0, 1, 2, 3 and x is Mr. Ucci’s age. (ii) Hair loss follows the hyperbolic assumption at fractional ages. (iii) The future lifetimes of the 3 hairs are independent. Calculate the probability that Mr. Ucci is bald (has no hair left) by age (x + 2.5). (0.1183) 8. For a 4year college, you are given the following probabilities for dropout from all causes: q = 0.15, q 1 = 0.10, q 2 = 0.05, q 3 = 0.01 Dropouts are uniformly distributed over each year. Calculate the temporary 1.5year complete expected college lifetime of a student entering the second year. (1.39) 2...
