# Multiple Event Probability Calculator

This Calculator Allows You to get the accurate probability of a multiple event.

### Formula:

Probability of event A that occurs P(A) = n(A) / n(S).Probability of event A that does not occur P(A') = 1 - P(A).

Probability of event B that occurs P(B) = n(B) / n(S).

Probability of event B that does not occur P(B') = 1 - P(B).

Probability that both the events occur P(A ∩ B) = P(A) x P(B).

Probability that either of event occurs P(A ∪ B) = P(A) + P(B) - P(A ∩ B).

Conditional Probability P(A | B) = P(A ∩ B) / P(B).

**Where,**

n(A) - Number of Occurrence in Event A,

n(B) - Number of Occurrence in Event B,

n(S) - Total Number of Possible Outcomes.
