    Consider the probability density function(pdf)

    p(x)={3/4(1-x^2) if |x|< or = 1
    0 otherwise

    which random variable X follows.Find the probability that 0</=X</=1/2?


    Will someone be kind enough to give me the full workings with explanation so I can study the solution for tomorrow's test.

    Can you do the basic calculus?
    \int_0^{\frac{1}<br /> {2}} {\frac{{3\left( {1 - x^{2} } \right)}}<br /> {4}dx} = ?
