Document Summary
Please write your name and student number at the spaces provided: Student id: there are ten (10) written-answer questions here and you are to answer all ten. Calculate the probability that a 25-year-old will survive another 25 years. In a population of newborn consisting of 70% males and 30% females, you are given: mortality for males follow de moivre"s law with = 100, mortality for females follow de moivre"s law with = 120. For a life (x), you are given x = 10, 000 and the following extract from a life table: k. An organism has a very short lifetime with its mortality described by the force of mortality. Calculate the probability that such an organism who has lived one year will survive another two years. You are given: the probability that (30) survives to reach age 50 is 0. 75, the probability that (30) dies between the ages of 50 and 65 is 0. 15, 30 = 1000.
