In total, there are 20 good outcomes in 1,000 possibilities, so the final probability is: P(X 27) = 20 / 1,000 = 0.02. One approach is to find the total number of possible sums. The probability of rolling a sum out of the set, not higher than X - the procedure is precisely the same as for the prior task, but we have to add only sums below or equal to the target. The probability of rolling at least X same values (equal to y) out of the set - the problem is very similar to the prior one, but this time the outcome is the sum of the probabilities for X=2,3,4,5,6,7. In this article, some formulas will assume that n = number of identical dice and r = number of sides on each die, numbered 1 to r, and 'k' is the combination value. Let's play a game!
