Probability of ab
Webb1 aug. 2024 · The probability of rolling a two is 11/36. The numerator here comes from the fact that there are six outcomes in which the first die is a two, six in which the second die is a two, and one outcome where both dice are twos. This gives us 6 + 6 - 1 = 11. The probability of rolling a three is 11/36, for the same reason as above.

WebbSince the probabilities of O, B, and AB together sum to 0.44 + 0.1 + 0.04 = 0.58, the probability of type A must be the remaining 0.42 (1 – 0.58 = 0.42): Probability Rule Two This example illustrates our second rule, which tells us that the probability of all possible outcomes together must be 1. Probability Rule Two: WebbTherefore, the probability of getting the score on the first die is six and the sum of the scores is at least 11 = 1/72.
