    Help me determine the quartiles of random variables

    F(x)=0 for x<0
    =1/3 for 0<=x<=1/2
    =1/2 for 1/2<=x<=3/4
    =1 for x>=3/4
    Determine,for the random variableX,the
    (a) upper quartile
    (b) lower quartile
    (c) propability mass function of X

    Hey lancelot.

    Hint: Try relating the quartiles to a probability expression (i.e. P(X < x) = q for some quartile value q).
