Question:

Let X and Y be two continuous random variables with joint probability density f(x, y). The joint distribution function F(a, b) is defined as follows:

Verify each of the following:

a. F (-∞, -∞) = F(-∞, y) = F(x, -∞) = 0

b. F (∞, ∞) = 1

c. If a≥ a1 and b2 ≥ b1 ,then F (a2, b2) - F (a1, b2) ≥ F (a2, b1) - F (a1, b1).
