On the other hand, if you place a bet on the number 7, your chances of winning are more substantial as there are more combinations to add up to the said number – 5 plus 2, 4 plus 3, and 6 plus 1. Thus, the only possible combination that can add up to the number 2 is 1 plus 1, so this number is less likely to get rolled. Others are rolled less frequently since there is a single combination that can add up to them. Certain numbers are more likely to come out as the number of combinations that can add up to them is greater.
