Probability a or b formula
WebbThe probability of A or B, occurs, but not both. Let A and B be two events. Suppose that P (A) = 0.4, P (B) = 0.5 and P (A intersect B) = 0.1.Find the probability that A or B occurs, … WebbFrom the above explanation, the P (A∪B) formula is: P (A∪B) = P (A) + P (B) - P (A∩B) This is also known as the addition theorem of probability. But what if events A and B are …

WebbProbability of A and B / A or B This probability is written P(B A), notation for the probability of B given A. In the case where events A and B are independent (where event A has no … WebbIf two events A and B are independent (this means that one event does not depend on the other), then the probability of both A and B occurring is found by multiplying the probability of A occurring by the probability of B occurring. The probability of picking a red OR yellow first is 1/3 + 1/3 = 2/3. The rule is:
WebbP (A B) may or may not be equal to P (A) (the unconditional probability of A ). If P (A B) = P (A), then events A and B are said to be independent: in such a case, knowledge about either event does not alter the likelihood of each other. P (A B) (the conditional probability of A given B) typically differs from P (B A).
