T.DIST.2T(x, degrees_freedom)

Returns the percentage points probability for the t distribution.

xThe number from the distribution.
degrees_freedomThe number of degrees of freedom.

Remarks

* Added in Excel 2010.
* This function replaces the TDIST function when "tails" = 2.
* The t distribution is a continuous distribution.
* If you want to return 'less than' or 'equal to' then you should use the T.DIST function.
* For the Microsoft documentation refer to support.office.com
