How to Use the PROB Function in Excel

This guide explains how to use PROB Function in Excel, including its syntax, required arguments, practical examples, and common errors.

Description: The function returns the probability that values in a range are between two limits.

Syntax: PROB (x_range, prob_range, [lower_limit], [upper_limit])

Inside:

- x_range: the range of numerical values of x with probability associated with it, which is a required parameter .

- prob_range: A set of probabilities associated with the values in x_range, is a required parameter.

- lower_limit: The lower bound of the value you want to calculate probability.

- upper_limit: Close on the option of the value you want to calculate probability.

Attention:

- If any value in Prob_name is not equal to 1 or has a value greater than 1 or less than or equal to 0 -> the function returns the #NUM! Error value !

- If upper_limit parameter is omitted -> function returns with probability lower_limit

- If x_range and prob_range have different data points -> the function returns the # N / A error value

For example:

Calculate Prob probability with the data described in the table below:

- In the cell to calculate the probability of entering the formula : = PROB ($ B $ 6: $ B $ 9, $ C $ 6: $ C $ 9, D6) (Here use the absolute address)

- Press Enter -> copy the formula for the remaining values:

- Case 1 of the values in prob_range is greater than 1 or less than 0 => The function returns the #NUM! Error value

Above are instructions and some specific examples when using the Prob function - the function returns the probability of values in a range between two limits in Excel.

Good luck!
