EXCEL PROB FUNCTION

The Excel PROB function computes the probability associated with a particular range given a list of values and a matching list of probabilities.

Syntax :

=PROB( x_rangeprob_range[lower_limit][upper_limit] )

Parameters :

  • X range – A set of values with associated probability.
  • Prob range – An array of chances matching to the x range values. (This arrays must be the same size as the x range array, as well as the prob range numbers must add up to one.)
  • Lower limit – The lower limit of the range of possibilities whereby the probability is to be calculated.
  • Upper limit – An optional number indicating the upper limits of the range for which you wish to compute the probability. (If the [upper limit] parameter is omitted, the function just returns the probability associated with the specified lower limit value.)

Step By Step Guide of PROB Function

Example :

Columns A and B of the spreadsheet below include a collection of values as well as the probabilities associated with them. In the spreadsheet’s cells C1-C3, these values and probabilities are sent to the Excel Prob functions.

  • #NUM! – Occurs if any of the following conditions are met: any value in the given prob range is 0 or more than one, or The specified prob range numbers do not add up to one.
  • #N/A! – Occurs if the x range and prob range arrays given are of various lengths.
