$p(x)=3x^2$ with $0 < x < 1$: 0 elsewhere.

$p(x)$ is the probability density function of the variables.

there are 3 independent variables $X_1$,$X_2$,$X_3$ with the distribution listed above

What is the probability exactly 2 are greater than $1/2$?

Thanks!

    If $p(x)$ is supposed to be the probability density function of each of the three random variables then you should probably say so.2011-09-23
