An insurance company offers its policyholder s a number of different premium payment opt ions. For a randomly selected policyholder, let X = the number of months between successiv e payments. The cdf of X is as follows: F(x) = 0 x < 1 0.30 1<x<3 0.40 3 ≤ x < 4 0.45 4≤x≤6 0.60 6≤ x < 12 1 x ≥ 12 (a) What is the pmf of X? (b) Find F(3.4) and F(6-) (c) Using just the cdf, compute P(3<X<4.5), P (2≤x≤6) and P(X>4)
