Question

A unbaised dice is rolled twice.The probability of positive difference (bigger smaller) between the two no.Is

Answer 1

Answer:

In order to get bigger then smaller, there are (6-1)+(5-1)+(4-1)+(3-1)+(2-1)+(1-1)=15 ways. (If the number of first dice is n, there are n-1 ways of getting a positive difference out of that particular number)

∴ Pr(Positive difference)=15/36=5/12

I think this should be the right answer.
