The value of a piece of factory equipment after three years of use is
100(0.5)^X where X is a random variable having moment generating function
M(t) = 1/1-2t , t<1/2
Calculate the expected value of this piece of equipment after three years of use.
Why can't you find the expected value by taking the derivative of the mgf at t=0 for this problem?
