Probability.ConditionalProbability Method

Calculates the conditional probability which is usually denoted by A|B.

public double ConditionalProbability(
int[] eventsA,
int[] eventsB
);

Parameters

eventsA: The first (sub)set of events given as an array of integers which corresponds to the index of the events within the set of all events.
eventsB: The second (sub)set of events defined as an array of integers which corresponds to the index of the events within the set of all events.

Return Value

The conditional probability of eventA, when eventB is known to occur.

Remarks

The conditional probability is the probability of an event A taking place when it is known that event B occurs.

Example

If the probability measure on a set is p = {0.2, 0.3, 0.4, 0.1}, and we have two sets of events A = {0, 2}, and B = {0, 3}, then the probability of A|B, will be 0.33.
