Let random variables X and Y denote the temperature and time in minutes it takes a diesel engine to start, respectively. The joint density for X and Y is (a) Find c. f(x, y) = c(4x+2y+1), 0x4, 0 y 2. (b)

(a) Find c. f(x, y) = c(4x+2y+1), 0x4, 0 y 2. (b) Find the marginal densities and decide whether or not X and Y are independent. (c) Find f(x|Y = 1).
