For a certain population the life expectancy T is an (approximate) exponential random variable with parameter \lambda =(1)/(60). a) what is the probability that a member of this population will die by the age of 50 ? b) what is the probability that a member of this population will live to be older than 100 ? c) What is the probability that a member of the population will live to be at least 90 , given that she/he is at least 75 ? You may express answers in terms of powers of e.

Suppose that the lifetime of an electronic component follows an exponential distribution with $\lambda=.1$ a. Find the probability that the lifetime is less than $10 .$ b. Find the probability that the lifetime is between 5 and $15 .$ c. Find $t$ such that the probability that the lifetime is greater than $t$ is .01
