Suppose that the random variables Y1 and Y2 have joint probability density function f
Chapter 5, Problem 5.14(choose chapter or problem)
Suppose that the random variables Y1 and Y2 have joint probability density function f (y1, y2) given by f (y1, y2) = $ 6y2 1 y2, 0 y1 y2, y1 + y2 2, 0, elsewhere. a Verify that this is a valid joint density function. b What is the probability that Y1 + Y2 is less than 1?
