CALC.prob(arrayx, arrayprob, lower_limit, upper_limit)

Returns the probability that values in a range are between two limits. Arrayx is the range of numeric values of x with which there are associated probabilities. Arrayprob is a set of probabilities associated with values in Arrayx. 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 not supplied the function returns the probability that values in Arrayx are equal to Lower_limit.

Example

CALC.prob([0,1,2,3], [0.2,0.3,0.1,0.4], 1, 3);

// returns 0.8 (probability that x lies within 1 and 3)
