If F(x) = $\frac { 1 } { 8 }$ X Is a Probability Density Function for 0 ≤ X

question 78

Short Answer

If f(x) = $\frac { 1 } { 8 }$ x is a probability density function for 0 ≤ x ≤ 4, find F(x), the corresponding cumulative distribution function and use it to find Pr(1 ≤ X ≤ 3).
Enter just a reduced fraction representing $\operatorname { Pr } ( 1 \leq X \leq 3 )$ Do not label.
