Probability Distribution Functions
Hello Friends (Bow)
I need help with a past exam paper question for statistics; it's from a first-year undergraduate paper. It goes like this:
The probability distribution of a random variable has the following density function:
(x) = cx^2(x-1) if 0=<x=<1
= o otherwise
and we are given a probability graph with a normal distribution with f(x) on the y-axis. x: 0=<x=<1 and f(x): 0=<x=<1 .
i) Show that c=30.
Can anyone please advise how I would go about solving this? I don't want the question solved for me, just a couple of hints.
Hope this is okay. Muchos gracios.
