### T.DIST(x, degrees_freedom, cumulative)

Returns the probability of getting less than or equal to a particular value in a t distribution (left tailed).

 x The number from the distribution. degrees_freedom The number of degress of freedom. cumulative The type of function to use:True = cumulative probability function (less than)False = probability density function (equal to)

#### Remarks

 * Added in Excel 2010.* This function replaces the TDIST function and to make it more consistent with the NORMDIST function.* T.DIST.RT was added in Excel 2010 to replace this function when "tails" = 1.* T.DIST.2T was added in Excel 2010 to replace this function when "tails" = 2.* The t distribution is a continuous distribution.* If "degrees_freedom" < 1, then #NUM! is returned* If "degrees_freedom" is not numeric, then #VALUE! is returned.* If "cumulative" = True, then the area under the curve to the left of "x" is returned. This uses the cumulative probability function.* If "cumulative" = False, then the height of the curve at "x" is returned. This uses the probability density function.* If "x" < 0, then #NUM is returned.* If "x" is not numeric, then #VALUE! is returned.* For the Microsoft documentation refer to support.office.com
