Total number of possible outcomes when two dice are thrown = 6 x 6= 36

(i) Total times when the sum is even = 18

P (getting an even number) = 18/36 = 1/2

(ii) Total times when the sum is 6 = 4

P (getting sum as 6) = 4/36 = 1/9

(iii) Total times when the sum is at least 6 i.e., greater than 5) = 15

P (getting sum at least 6) = 15/36 = 5/12
