Answer 1

HEY MATE

HERE IS YOUR ANSWER

The possible outcomes to get sum as 10 = (1,3,6), (1,4,5),(1,5,4),(1,6,3),(2,2,6),(2,3,5),(2,4,4),(2,5,3),(2,6,2),(3,1,6),(3,2,5),(3,3,4),(3,4,3),(3,5,2),(3,6,1),(4,1,5),(4,2,4),(4,3,3),(4,4,2),(4,5,1),(5,1,4),(5,2,3),(5,3,2),(5,4,1),(6,1,3),(6,2,2),(6,3,1)

Therefore,total favourable outcomes= 27

Total possible outcomes= 216

Probability of getting sum as 10= 27/216 = 1/8
