If X and Y are independent exponential random
variables, each having parameter λ = 6, find the joint
density function of U = X + Y and
V = e 2X. The required joint density function is of the form fU,V (u, v) =
|
(a) | Enter the function g(u, v) into the answer box below. |
(b) | Enter the function h(v) into the answer box below. |
(c) | Enter the value of a into the answer box
below. |
Solution:-
Given that
x and y are exponential random variable each having parameter .
density function of X,
joint density of x, y
, x> 0, y > 0
,
(x and y are independent)
By the method of transforms on
f(u, v) is the joint density of u and v
(a) | Enter the function g(u, v) into the answer box below |
(a)
so
(b) | Enter the function h(v) into the answer box below. |
So the function h(v) is given that
(c) | Enter the value of a into the answer box below. |
value of "a" into the answer box below
a = 1
