Let T be the random variable that models the lifespan of a cellphone battery (in months). It is known that T~Exp (1/32) a) What is the expected lifespan of the battery? b) What is the probability that the battery will run at least twice it's expected lifespan? c) What is the probability that the battery will run at most twice it's expected lifespan? d) If the battery dies within the first year, the manufacturer of the cellphone is abided by law to replace the whole cellphone free of charge for the buyer. What are the chances of this happening? e) Calcukate the 25% Quantile & interpret it.
