Probability of a b
WebbThe probability of an event A is the number of ways event A can occur divided by the total number of possible outcomes. The probability of an event A, symbolized by P (A), is a number between 0 and 1, inclusive, that measures the likelihood of an event in the following way: If P (A) > P (B) then event A is more likely to occur than event B.

WebbThe conditional probability of A given B, denoted P(A ∣ B), is the probability that event A has occurred in a trial of a random experiment for which it is known that event B has definitely occurred. It may be computed by means of the following formula: P(A ∣ B) = P(A ∩ B) P(B) Example 4.3.1: Rolling a Die A fair (unbiased) die is rolled. WebbWe apply P(A ∩ B) formula to calculate the probability of two independent events A and B occurring together. It is given as, P(A∩B) = P(A) × P(B), where, P(A) is Probability of an …
