## Function name:

PROB

## Category:

Statistical Analysis

## Summary:

Returns the probability that values in a range are between two limits.

## Syntax:

PROB(**Data**; **Probability**; **Start**; **End**)

## Returns:

## Arguments:

**Data** is the array or range of data in the sample.

**Probability** is the array or range of the corresponding probabilities.

**Start** is the start value of the interval whose probabilities are to be summed.

**End** (optional) is the end value of the interval whose probabilities are to be summed. If this parameter is missing, the probability for the **Start** value is calculated.

If there is no **End** value, this function calculates the probability based on the principle that the **Data** values are equal to the value of **Start**.

## Additional details:

## Examples:

=PROB(A1:A50;B1:B50;50;60) returns the probability with which a value within the range of A1:A50 is also within the limits between 50 and 60. Every value within the range of A1:A50 has a probability within the range of B1:B50.
