Enter the probability of event A and event B into the Calculator. The calculator will evaluate the Overlapping Probability.

## Overlapping Probability Formula

OP = P(A) + P(B) - P(a+B)

Variables:

- OP is the Overlapping Probability ()
- P(A) is the probability of event A
- P(B) is the probability of event B
- P(a+B) is the probability of both events

To calculate Overlapping Probability, add the probability of event A to that of event B, then subtract the probability of both events from the result.

## How to Calculate Overlapping Probability?

The following steps outline how to calculate the Overlapping Probability.

- First, determine the probability of event A.
- Next, determine the probability of event B.
- Next, determine the probability of both events occuring.
- Next, gather the formula from above = OP = P(A) + P(B) – P(a+B).
- Finally, calculate the Overlapping Probability.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

probability of event A = 3

probability of event B = 5

probability of A and B = 2
