Q5 An electronic device consists of two components. Let

x

and

Y

[years] be the times to failure of the first and second components, respectively. Assume that

(x,Y)

has the density

f(x,y)=4e^(-2(x+y))

if

x,y

both are

>0

and 0 otherwise. (a) Are

x

and

Y

dependent or independent? (b) Find the densities of the marginal distributions. (c) What is the probability that the first component will have a lifetime of 2 years or longer?
