Probability when two events are independent

WebbDefinition (s): Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B (i.e., P (A and B) = P (A)P ... Webb10 feb. 2016 · Two events or distributions are defined as independent if their joint probabilities equal the product of their individual probabilities. This may seem a mouthful, so a simple numerical example will help. If the chance that ‘x’ has a value of 3 is 0.2 and ‘y’ has a value of 2 is 0.3, then the chance ‘x’ is 3 and ‘y’ is 2 is 0.2 × 0.3 = 0.06.

WebbThe two events are said to be independent events if the outcome of one event does not affect the outcome of another. Or, we can say that if one event does not influence the probability of another event, it is called an independent event. Independent events in probability reflect real-life events.

An event A is said to be independent of another event B if the probability of occurrence of one of them is not affected by the occurrence of the other. Suppose if we draw two cards from a pack of cards one after the other.

Webb26 mars 2024 · The 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: (3.3.1) P ( A ∣ B) = P ( A ∩ B) P ( B)

Webb10 mars 2024 · The calculation P ( A) ∗ P ( B) = 9 16 clearly gives a different answer. I think this means that events A and B are not independent. Two events are dependent if the outcome of the first event affects the outcome of the second event, so that the probability is changed. So conceptually, how/why is A affecting B (or vice-versa)?

This is the definition of independence. The other conditions, P ( A ∣ B) = P ( A) etc., are not quite equivalent.
