A die has two faces each with number 1, three faces each with number 2 and one face with number 3. If die rolled once determine: i.                P(2)   ii. P(1 or 3)  iii. P(not 3)

Explanation

Total number of faces =6

(i) Number faces with number ′2′=3

∴`P(2)=3/6​=1/2`

​

(ii) `P(1or3)=P(not2)=1−P(2)
⇒P(1or3)=1−1/2​=1/2`
​

(iii) Number of faces with number ′3′=1
