3 A small petrol station is supplied with petrol once a week. Assume that its volume X of potential sales(in units of 10, 000 litres) has the probability density function f(r) = 6(x - 2)(3 - ) for 2 < I<3and f(x) = 0 otherwise. Determine the mean and the variance of this distribution. What capacitymust the tank have for the probability that the tank will be emptied in a given week to be 5%?
