- 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: REFER IMAGE a. What is the pmf of X?b. Using just the cdf, compute P(3 ≤ x ≤ 6) and P(4 ≤ X)Find the ordinary generating function for the number of partitions of n in which no part occurs more than 3 times.The t-table has entries for areas of 0.10, 0.05, 0.025, 0.01, and 0.005. In contrast, the ? 2 -table has entries for those areas and for 0.995, 0.99, 0.975, 0.95, and 0.90. Explain why the t-values corresponding to these additional areas can be obtained from the existing t-table but must be provided explicitly in the ? 2 -table.
