Let X be a continuous random variable with PDF
\({f_x}\left( x \right) = \left\{ {\begin{array}{*{20}{c}} {4{x^3}\;\;\;\;0 < x \le 1}\\ {0\;\;\;\;\;otherwise} \end{array}} \right.\)
The value of \(P\left( {X \le \frac{2}{3}{\rm{|}}X > \frac{1}{3}} \right)\;\)is
1
\(\frac{1}{9}\)
2
\(\frac{5}{{27}}\)
3
\(\frac{5}{{16}}\)
4
\(\frac{3}{{16}}\)
