Q130
If X is a continuous random variable whose probability density function is given by\[ f ( x ) = \ array*20c K ( 5 x - 2 x^2 )&0 x 2 \\ 0& otherwise array .\] then P(x > 1) is
If X is a continuous random variable whose probability density function is given by
{\text{f}}\left( {\text{x}} \right) = \left\{ {\begin{array}{*{20}{c}} {{\text{K}}\left( {5{\text{x}} - 2{{\text{x}}^2}} \right)}&{0 \leqslant {\text{x}} \leqslant 2} \\ 0&{{\text{otherwise}}} \end{array}} \right.
then P(x > 1) is
{\text{f}}\left( {\text{x}} \right) = \left\{ {\begin{array}{*{20}{c}} {{\text{K}}\left( {5{\text{x}} - 2{{\text{x}}^2}} \right)}&{0 \leqslant {\text{x}} \leqslant 2} \\ 0&{{\text{otherwise}}} \end{array}} \right.
then P(x > 1) is
