<p>The <b>PROB</b> function is one of the statistical functions. It is used to return the probability that values in a range are between lower and upper limits.</p>
<pstyle="text-indent: 50px;"><b><em>x-range</em></b> is the selected range of cells containing numeric values you want to associate the probabilities with.</p>
<pstyle="text-indent: 50px;"><b><em>probability-range</em></b> is a set of probabilities associated with values in <b><em>x-range</em></b>, the selected range of cells containing numeric values greater than 0 but less than 1. The sum of the values in <b><em>probability-range</em></b> should be equal to 1, otherwise the function will return the <b>#NUM!</b> error.</p>
<pclass="note"><b>Note</b>: <b><em>x-range</em></b> should contain the same number of elements as <b><em>probability-range</em></b>.</p>
<pstyle="text-indent: 50px;"><b><em>lower-limit</em></b> is the lower bound of the value, a numeric value entered manually or included into the cell you make reference to.</p>
<pstyle="text-indent: 50px;"><b><em>upper-limit</em></b> is the upper bound of the value, a numeric value entered manually or included into the cell you make reference to. It is an optional argument. If it is omitted, the function will return the probability equal to <b><em>lower-limit</em></b>.</p>
