PROB function: Description, Usage, Syntax, Examples and Explanation

Syntax of PROB function

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

The PROB function syntax has the following arguments:

• X_range: The range of numeric values of x with which there are associated probabilities.
• Prob_range: A set of probabilities associated with values in x_range.Lower_limit    Optional. The lower bound on the value for which you want a probability.
• Upper_limit(Optional): The optional upper bound on the value for which you want a probability.

Explanation of PROB function

• If any value in prob_range ≤ 0 or if any value in prob_range > 1, PROB returns the #NUM! error value.
• If the sum of the values in prob_range is not equal to 1, PROB returns the #NUM! error value.
• If upper_limit is omitted, PROB returns the probability of being equal to lower_limit.
• If x_range and prob_range contain a different number of data points, PROB returns the #N/A error value.
