The lifetime, T (in years) of an electrical item has reliability (survival) function G(t) = {(t + 1)-3,t 20 to. t< 0 (a) Find the probability that the electrical item has a lifetime less than two years. (b) Suppose you buy one of these items today. If it is working two years from today, what is the chance that it will still be working five years from today? (c) Calculate the MTTF of the electrical item. You may find the substitution u = t +1 useful in your calculations.
