PROB

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.

Syntax

PROB(x_range,prob_range,lower_limit,upper_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.

Remarks

• 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.

Examples

PROB({0,1,2,3},{0.2,0.3,0.1,0.4},2) equals 0.1

PROB({0,1,2,3},{0.2,0.3,0.1,0.4},1,3) equals 0.8
