Regarding continuous random variable

  1. Sep 19, 2006 #1
    Here's the qn random variable X follows uniform distribution [-a,a] and random variable Y is defined as Y=e^x find E(Y)

    i figure that E(Y)=E(e^x) but somehow cant carry on from there can anyone help?

    The expectation of a continuous random variable Y is defined by [tex]\int_{-\infty}^{+\infty}xf(x)dx[/tex], where f(x) is the probability density function of the random variable Y. Follow the definition. :smile:
