An insurance company offers its policyholders a number of different premium payment options. For a randomly selected policyholder, let X be the number of months between successive payments. The PMF of X is given as follows: x 2 4 6 P(x) 0.3 0.3 0.4 Calculate E[X(X-1)] Determine the CDF (Cumulative Distribution Function) of X.

An insurance company offers its policyholders a number of different premium payment options. For a randomly selected policyholder, let X = the number of months between successive payments. The cdf of X is as follows: F(x) = 0, x < 1 0.38, 1 <= x < 3 0.49, 3 <= x < 4 0.53, 4 <= x < 6 0.87, 6 <= x < 12 1, 12 <= x (a) What is the pmf of X? (b) Using just the cdf, compute P(3 <= X <= 6) and P(4 <= X).

An insurance company offers its policyholders a number of different premium payment options. For a randomly selected policyholder, let X be the number of months between successive payments. The CDF of X is: - Fx(x) = 0.4, for 1 <= x < 3 - Fx(x) = 0.6, for 3 <= x < 5 - Fx(x) = 0.8, for 5 <= x < 7 - Fx(x) = 1, for x >= 7 What proportion of policyholders pay their premium less than every 3 months and more than every 5 months?
