Question : A continuous random variable has a probability density function
f(x) =
Find the cumulative distribution
find the E[X] and Var X
Solution
The random variable is a uniform distribution random variable
Cumulative Distribution function =
But i dont know how to prove the above ......
My work :
=
= = 0 ...............Is this correct ?
E[X] =
= dx .............What should i do now integrate with and or what
And what about the Var X as well??
