The lifetimes, in months, of two components in a system, denoted X and Y , have joint

Question:

The lifetimes, in months, of two components in a system, denoted X and Y , have joint probability density function.

x > 0 and y > 0 otherwise f(x) = 4xye-(2r+y)

a. What is the probability that both components last longer than one month?

b. Find the marginal probability density functions f_X (x) and f_Y (y).

c. Are X and Y independent? Explain.
