# Math Help - beta random variable

1. ## beta random variable

If x is a beta random variable with pdf ,
f(x)=k*X^5*(1-x) where X [0,1]

Find the CDF and the MGF.

This is a pdf of beta random variable, I have never seen this before.
Can someone please give me some hints?

Apply the usual definitions of the cdf and the mgf and do the integrations. Where do you get stuck?
