*In <math>PROB(xr,pr,ll,ul), xr</math> is the array of numeric values which there are associated probabilities,<math>pr</math> is a set of probabilities associated with <math> xr,ll </math> is the lower limit of the probability and <math>ul</math> is the upper limit of the probability.

*In <math>PROB(xr,pr,ll,ul)</math>, <math>xr</math> is the array of numeric values which there are associated probabilities,<math>pr</math> is a set of probabilities associated with <math> xr</math>, <math>ll</math> is the lower limit of the probability and <math>ul</math> is the upper limit of the probability.

*Here <math>ul</math> is optional.When we are omitting the value of ul, then the function simply returns the probability associated with the value of the given ll.

*Here <math>ul</math> is optional.When we are omitting the value of <math>ul</math>, then the function simply returns the probability associated with the value of the given <math>ll</math>.

*This function will return the result as error when
