# Question: Let T1 and T2 be random times for a company

Let T1 and T2 be random times for a company to complete two steps in a certain process. Say T1 and T2 are measured in days and they have the joint pdf that is uniform over the space 1 < T1 < 10, 2 < T2 < 6, T1 + 2T2 < 14. What is P(T1 + T2 > 10)?

Show that in the bivariate situation, E is a linear or distributive operator. That is, for constants a1 and a2, show that Let X have a uniform distribution on the interval (0,1). Given that X = x, let Y have a uniform distribution on the interval (0, x + 1). (a) Find the joint pdf of X and Y. Sketch the region where f(x, y) > 0. (b) Find E(Y | ...Let X and Y have a bivariate normal distribution with μX = 70, σ2X = 100, μY = 80, σ2Y = 169, and ρ = 5/13. Find (a) E(Y | X = 72). (b) Var(Y| X = 72). (c) P(Y ≤ 84, | X = 72).
