PROB (Xs,Probabilities,lower_limit,upper_limit)

• $Xs$ is the array of x range of values in the function.
• $Probabilities$ is the set of probabilities.
• $lowerlimit$ is the lower limit
• $upperlimit$ is the upper limit value.

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 $PROB(Xs,Probabilities,lowerlimit,upperlimit)$, $Xs$ is the array of numeric values which there are associated probabilities, $Probabilities$ is a set of probabilities associated with $Xs$, $lowerlimit$ is the lower limit of the probability and $upperlimit$ is the upper limit of the probability.
• Here $upperlimit$ is optional. When we are omitting the value of $upperlimit$, then the function simply returns the probability associated with the value of the given $lowerlimit$.
• This function will return the result as error when

1.Any one of the value is non-numeric.
2.Any value of $Probabilities\leq 0$ or $Probabilities>1$
3.The values in the given $Probabilities$  do not adding  up to 1
4.$Xs$ and $Probabilities$ is of different number of data points.
