is a proper joint density function if, over its support, is non-negative and the integral of
is 1. The first condition is easily met as long as
. To meet the second condition, we require
b. Find the marginal joint density of and
by integrating the joint density with respect to
:
Then
c. This probability can be found by simply integrating the joint density:
Consider the given equations:
The first equation is as:
So,
=
Multiplying the given fractions, we get as
=
Now, consider the second equation as:
Multiplying by '3' to both the sides of the equation, we get
So, the number which best completes both the equations is .
