How do I find PMF if I have CDF? For example:
<br /> F_X (x)=\left\{\begin{array}{cc}0,&\mbox{ if }x\leq -1<br /> \\0.2, & \mbox{ if } -1\leq x < 0<br /> \\0.7, & \mbox{ if } 0\leq x < 1<br /> \\1, & \mbox{ if } x \geq 1<br /> \end{array}\right.
<br /> F_X (x)=\left\{\begin{array}{cc}0,&\mbox{ if }x\leq -1<br /> \\0.2, & \mbox{ if } -1\leq x < 0<br /> \\0.7, & \mbox{ if } 0\leq x < 1<br /> \\1, & \mbox{ if } x \geq 1<br /> \end{array}\right.
