Google Sheets

The POISSON.DIST function in Google Sheets is used to calculate the probability of a given number of events occurring in a given time period, using the Poisson distribution. The function takes 3 arguments: the number of events, the time period, and a boolean indicating whether or not to use the lambda parameter. If the lambda parameter is not used, the function defaults to 1.0. The function returns a value between 0 and 1, indicating the probability of the given number of events occurring in the given time period.

The syntax of the POISSON.DIST function in Google Sheets is as follows:

=POISSON.DIST(x, mean, standard_deviation)

Where x is the number of events, mean is the expected number of events, and standard_deviation is the standard deviation.

The Poisson distribution is a discrete probability distribution that models the number of events that occur in a given interval of time or space. It is used to calculate the probability of a certain number of events occurring in a given interval. The Poisson.DIST function in Google Sheets can be used to calculate the probability of a certain number of events occurring in a given interval. The function takes two parameters: the number of events and the interval. The function will return the probability of exactly the number of events that occur in the given interval.

POISSON.DIST should not be used in Google Sheets when the number of events is greater than 20,000, as it will return an incorrect value. If the number of events is less than 20,000, POISSON.DIST will return the correct value.

There are a few similar formulae to POISSON.DIST in Google Sheets. The first is the NORM.DIST function, which calculates the normal distribution for a given set of data. The second is the BINOM.DIST function, which calculates the binomial distribution for a given set of data. The third is the EXPON.DIST function, which calculates the exponential distribution for a given set of data. And the fourth is the WEIBULL.DIST function, which calculates the Weibull distribution for a given set of data.
