Webb5 jan. 2024 · Given two events, A and B, to “find the probability of A and B” means to find the probability that event A and event B both occur. We typically write this probability in one of two ways: P(A and B) – Written form; P(A∩B) – Notation form; The way we calculate this probability depends on whether or not events A and B are independent or ... Webb8 feb. 2024 · To find the percentage of a determined probability, simply convert the resulting number by 100. For example, in the example for calculating the probability of rolling a “6” on two dice: P (A and B) = 1/6 x 1/6 = 1/36. Take 1/36 to get the decimal and multiple by 100 to get the percentage: 1/36 = 0.0278 x 100 = 2.78%.
