Total number of outcomes when a die is thrown once = 6 (1,2,3,4,5,6)(i) even prime number = 2
Number of favourable outcomes = 1
Probability(P)= Number of favourable outcomes/total number of outcomes
P(getting a even prime number)= ⅙
(ii) Numbers divisible by 2 are = 2,4 & 6
Number of favourable outcomes= 3
Probability(P)= Number of favourable outcomes/total number of outcomes
P(getting a even number divisible by 2)=3/6= ½
(iii) multiples of 3 are 3 and 6
Number of available outcomes = 2
Probability(P)= Number of favourable outcomes/total number of outcomes
P(getting a even multiple of 3)= 2/6= ⅓
