The Probability Density Function for a Random Variable X Is $f ( x ) = \frac { 2 \ln x } { ( \ln 4 ) ^ { 2 } x }$

Short Answer

The probability density function for a random variable X is $f ( x ) = \frac { 2 \ln x } { ( \ln 4 ) ^ { 2 } x }$ , $1 \leq x \leq 4$ Find $\operatorname { Pr } ( 1 \leq X \leq 2 )$ Enter just a reduced fraction.
