Directions: Suppose that the average life span of anelectronic component is 72 months and that the life spansare exponentially distributed.1. Find the probability that a component lasts for morethan 12 months.Probability =2. The reliability function r(t) gives the probability that acomponent will last for more than t months. Computer(t) in this case.r(t):=

6 Trout population Suppose 200 trout are caught, tagged, and released in a lake's general population. Let T denote the number of tagged fish that are recaptured when a sample of n trout are caught at a later date. The validity of the mark- recapture method for estimating the lake's total trout popula- tion is based on the assumption that Tis directly proportional to n. If 10 tagged trout are recovered from a sample of 300, estimate the total trout population of the lake.
