Returns the probability that values in a range are between two limits. If upper_limit is not supplied, returns the probability that values in x_range are equal to lower_limit.
X_range is the range of numeric values of x with which there are associated probabilities.
Prob_range is a set of probabilities associated with values in x_range.
Lower_limit is the lower bound on the value for which you want a probability.
Upper_limit is the optional upper bound on the value for which you want a probability.
- 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 ¹ 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.
