Probability Density Function

  1. Apr 19, 2005 #1
    Hi Guys,

    I am having some trouble trying to solve a probability density function question.

    ...If the density function is: f(x) = 9x^3, 0 < x 1. What is the conditional probability of P(X > 0.2 | X <0.6) ??

    Any help would be greatly appreciated :)

    Find the probability that X is greater than 0.2 and less than 0.6 and divide that by the probability that X is less than 0.6.
