Which Excel formula calculates Poisson probabilities?

The correct choice is based on the specific function name used in Excel for calculating Poisson probabilities. The formula =POISSON.DIST(x, mean, TRUE/FALSE cumulative) is indeed the correct representation of the function that calculates Poisson distribution probabilities.

This function takes three arguments: 'x' represents the number of events for which you want to compute the probability, 'mean' is the average number of events that occur in a given interval, and the last argument indicates whether you want the cumulative distribution function (TRUE) or the probability mass function (FALSE). This clear structure allows users to easily specify their desired probability computation within the context of a Poisson distribution.

Understanding this formula is essential for applications in various fields, such as business and engineering, where modeling events that occur randomly over a fixed interval is necessary. The correct identification of this function is crucial in statistical analyses that involve discrete random variables.
