Chapter 11.2, Problem 24E

Use the cumulative distribution function from Problem 20 to find the value of a that satisfies each equation.

(A)     $P\left(0\le X\le x\right)=\frac{1}{8}$

(B)     $P\left(0\le X\le x\right)=\frac{1}{64}$

20.    Find and graph the cumulative distribution function associated with the function in Problem 10.

10.     $f\left(x\right)=\{\begin{array}{cc}\frac{1}{9}{x}^2& \text{if }0\le x\le 3\\ 0& \text{otherwise}\end{array}$
