A die has two faces each with number $^{\prime}1^{\prime}$ , three faces each with number $^{\prime}2^{\prime}$ and one face with number $^{\prime}3^{\prime}$. If die is rolled once, determine $P($ not $3)$

Total number of faces $=6$

Number of faces with number $^{\prime}3^{\prime}=1$

$\therefore  $ $P(3)=\frac{1}{6}$

Thus, $P($ not $3)=1-P(3)=\frac{1}{6}=\frac{5}{6}$
