4.5.-4.8.
Санамсаргүй хэмжигдэхүүний нягтын функц өгөгдөв. (а) $c$ тогтмолыг ол. (b) Тархалтын функцийг бич. (с) $P(a\leq X\leq b)$ магадлалыг ол. (d) $F(x)$, $f(x)$ функцүүдийн график байгуул.
4.5. $f(x)=\left\{\begin{array}{lcc}
c(x^2+2x) & x\in [0;1] & \\
0 & x\notin [0;1] & a=0 \qquad b=0,5
\end{array}\right.

4.6. $f(x)=\left\{\begin{array}{lcc}
2c\sin{x} & x\in [0;\pi/2] & \\
0 & x\notin [0;\pi/2] & a=0 \qquad b=\pi/4
\end{array}\right.
