Finding Probability Using CDF

  1. Oct 24, 2007 #1
    How do I find PMF if I have CDF? For example:

    [tex]
    F_X (x)=\left\{\begin{array}{cc}0,&\mbox{ if }x\leq -1
    \\0.2, & \mbox{ if } -1\leq x < 0
    \\0.7, & \mbox{ if } 0\leq x < 1
    \\1, & \mbox{ if } x \geq 1
    \end{array}\right.[/tex]

    f(x) = [itex]\Delta F(x)/\Delta x[/itex]
