Theorem Of Total Probability - Definiton, Formula, Proof

WebFeb 8, 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%.
