The “More-Likely-Than-Not” distribution on the unit internal has density function f (x) = kx2(1 − x) for 0 < x < 1. It is the “go to” distribution that TV weatherpersons use when they need to state tomorrow's probability of rain on a given day during the months November–March. They draw a random decimal from this distribution and announce it as the required probability. (a) Find the constant k for which f (x) is a valid density. (b) Compute the mean of the “MLTN” distribution. (c) Compute the variance of the distribution.
