Description
- This function gives the probability that values in a range of given limits.
- Probability is the likelihood that an event will occur.
- Probabilities can be used to describe frequencies of outcomes in random experiments.
- In , is the array of numeric values which there are associated probabilities, is a set of probabilities associated with , is the lower limit of the probability and is the upper limit of the probability.
- Here is optional.When we are omitting the value of , then the function simply returns the probability associated with the value of the given .
- This function will return the result as error when
, 1.Any one of the value is non-numeric. 2.Any value of or 3.The values in the given do not adding up to 1 4. and is of different number of data points.
