Explanation:
Detailed explanation-1: -The probability of getting 9 as the sum when 2 dice are thrown is 1/9.
Detailed explanation-2: -About 36 different combos are present for the two dice i.e. 6 possibilities for the first dice and 6 possibilities for the second. Therefore, the probability that the sum is 9 or higher is 5/18.
Detailed explanation-3: -That makes 36 possible outcomes, each with probability 1/36. Four of 36 outcomes sum to 9. The probability of this event is 4/36 (1/9, or 11.11%). A pair of dice is tossed, what is the probability of getting a sum of at least 9?
