### FDIST(x, degrees_freedom1, degrees_freedom2)

Returns the probability of getting less than or equal to a particular value in an f distribution (no cumulative) (left tailed).

 x The number from the distribution. degrees_freedom1 The numerator degrees of freedom. degrees_freedom2 The denominator degrees of freedom.

#### Remarks

 * F.DIST was added in Excel 2010 to replace this function.* F.DIST.RT was added in Excel 2010 to replace this function.* The f distribution is a continuous distribution.* The f distribution is not symmetrical.* If "x" < 0, then #NUM! is returned.* If "x" is not numeric, then #VALUE! is returned.* If "degrees_freedom1" < 1, then #NUM! is returned.* If "degrees_freedom1" = 10^10, then #NUM! is returned.* If "degrees_freedom1" is not an integer, it is truncated.* If "degrees_freedom1" is not numeric, then #VALUE! is returned.* If "degrees_freedom2" < 1, then #NUM! is returned.* If "degrees_freedom2" = 10^10, then #NUM! is returned.* If "degrees_freedom2" is not an integer, it is truncated.* If "degrees_freedom2" is not numeric, then #VALUE! is returned.* All the values are greater than zero.* In Excel 2010 the accuracy of this function was improved.* For the Microsoft documentation refer to support.office.com
