Tuff Rubbers Tire Company has developed a new all-season tire. The lifetime of these tires, X, follows an exponential distribution with a mean of 40,000 km. (a) What is the probability a tire needs to be replaced within the first 10,000 km of use? (b) What is the median lifetime of these tires? (c) How does the median compare to the mean? Could you have guessed this would be the case prior to answering part (b)? Explain
