Unformatted text preview: (iii) There is an 8% chance of a 70year old surviving the next 30 years. (iv) All lives are independent and have the same expected mortality. Calculate the probability that an 80year old will survive to age 90. (0.5) ————THERE ARE MORE PROBLEMS ON THE BACK ———— 1 6. You are given: t  q = 0.10 for t = 0, 1, . .., 9. Calculate: 2 p 5 . (0.6) 7. Suppose mortality follows modiﬁed (or generalized) de Moivre’s Law , where: s ( x ) = ( ωx ω ) α for 0 ≤ x ≤ ω , α > 0. Note that regular de Moivre’s Law is a special case of this modiﬁed law with α = 1. Show: t p x = ( ωxt ωx ) α for 0 ≤ t ≤ ( ωx ), α > 0. 2...
