Question

A die thrown once. Find the probability of getting 

(i) a prime number; 

(ii) a number lying between 2 and 6; 

(iii) an odd number.

Answer 1

Possible event when a die is thrown: 1, 2, 3, 4, 5, 6 

∴ n(S) = 6 

(i) Probability of getting a Prime number : 2, 3, 5 

∴ n(A) = 3

(ii) A number lying between 2 and 6 : 3, 4, 5 

∴ n(B) = 3
