What is the probability that getting a total of the numbers on the dice is at least 23?

When 4 dice are rolled, the total number of outcomes is 6^4 = 1296. To get a sum of at least 23, the possible sums are 23 and 24. For sum = 24, all four dice must show 6, giving 1 outcome. For sum = 23, exactly one die shows 5 and the rest show 6, giving 4 outcomes (choosing which die shows 5). Total favorable outcomes = 1 + 4 = 5. Therefore, the probability = 5/1296.
