एक यादृच्छिक चर X के PDF पर विचार करें:
\({\rm{f}}\left( {\rm{x}} \right) = \left\{ {\matrix{ {k,a \le x \le b} \cr {0,otherwise} \cr } } \right.\)
जहाँ k एक नियत मान है,
1
\({1 \over {\left( {b - a} \right)}}\)
2
\({1 \over {{{\left( {a - b} \right)}^2}}}\)
3
\({1 \over {\left( {a - b} \right)}}\)
4
\(a - b\)
