$$f ( x ) = \left\{ \begin{array} { l r } \frac { 1 } { 8 } & \text { for } 0 \leq x \leq 8 \\0 & \text { otherwise }\end{array} \right.$$

Short Answer

$$f ( x ) = \left\{ \begin{array} { l r } \frac { 1 } { 8 } & \text { for } 0 \leq x \leq 8 \\0 & \text { otherwise }\end{array} \right.$$ is a probability density function for a particular random variable X . Use integration to find $P ( 1 \leq x \leq 4 )$ rounded to the nearest hundredth
