A die has six numbers: 1, 2, 3, 4, 5, 6
∴ Number of possible outcome = 6
(i) Number of favourable outcome = an even number i.e. 2, 4, 6 which are 3 in numbers
∴ P(E) = Number of favourable outcome/Number of all possible outcome
= 3/6 = 1/2
(ii) & (iii) Number of favourable outcome = not an even number i.e. odd numbers :
1, 3, 5 which are 3 in numbers
∴ P(E) = Number of favourable outcome/Number of all possible outcome
= 3/6 = 1/2
