<div class="raw-html-embed">	<p>The <b>POISSON.DIST</b> function is one of the <a href="../../docs/userguides/spreadsheet_editor/InsertFunction.aspx#statistical" onclick="onhyperlinkclick(this)">statistical functions</a>. It is used to return the Poisson distribution; a common application of the Poisson distribution is predicting the number of events over a specific time, such as the number of cars arriving at a toll plaza in 1 minute.</p>

Argument	Description
x	The number of events, a numeric value greater than 0.
*mean*	The expected numeric value greater than 0.
*cumulative*	The form of the function, a logical value: TRUE or FALSE. If *cumulative* is TRUE, the function will return the cumulative Poisson probability; if FALSE, it will return the Poisson probability mass function.
