Question

Let the density function of a continuous random variable X be \begin{equation} f(x) = \begin{cases} 0 & \text{if } x < 0\\ \frac{2x}{bc} & \text{if } 0 \le x \le c\\ \frac{2(b-x)}{b(b-c)} & \text{if } c \le x \le b\\ 0 & \text{if } x > b \end{cases} \end{equation} a) Find the CDF of X.

          Let the density function of a continuous random variable X be
\begin{equation*}
f(x) = \begin{cases}
0 & \text{if } x < 0\\ 
\frac{2x}{bc} & \text{if } 0 \le x \le c\\ 
\frac{2(b-x)}{b(b-c)} & \text{if } c \le x \le b\\ 
0 & \text{if } x > b
\end{cases}
\end{equation*}
a) Find the CDF of X.

Let the density function of a continuous random variable X be

f(x) =
0 if x < 0
(2x)/(bc) if 0 ≤ x ≤ c
(2(b-x))/(b(b-c)) if c ≤ x ≤ b

0 if x > b

a) Find the CDF of X.
