Question

A pair of dice is tossed. How do you find the probability with sum of the numbers if not 8?

Answer 1

Probability of sum (not `8`) is `31/36`

Explanation:

Dice has `6` faces.

Total number of outcomes for 2 dice is `6*6 =36`

Sum `8` can be in `(2,6) , (3,5) , (4,4) ,(5,3) ,(6,2) = 5` ways.

So sum `!= 8` is possible in `36-5 =31` ways.

Probability of sum (not `8`) is `31/36` [Ans]
