The time T in days between printer jams is exponentially distributed with parameter á = 1.2.
(a) Determine the expected time between printer jams? What is the standard deviation of the time between printer jams?
(b) Determine the median time between printer jams (the value M such that there is equal probability of T being smaller or larger that M)?
(c) Determine the probability that there would be more than two printer jams in one day? That there would be less than five printer jams in two days?
