TDIST(Number,DegreeOfFreedom,Tail),

$Number$ is the numeric value to find the distribution.
$DegreeOfFreedom$ is the degrees of freedom.
is the number of tails.
- TDIST(),returns the Student t-distribution.

Description

This function gives the value of the T-Distribution.
It is the continuous probability distributions.
The T-Distribution is also called Students T-Distribution.
This is the symmetric distribution like the Normal Distribution.
It is used when making inferences about a population mean when the population standard deviation is not known.
In $TDIST(Number,DegreeOfFreedom,Tail)$ , $Number$ is the numeric value to find the value of the distribution.
$DegreeOfFreedom$ is the integer which is indicating the number of degrees of freedom and $Tail$ is indicating the number of distribution tails.
Suppose Tail=1, then this distribution is One-Tailed Distribution and Tail=2, then this is Two-Tailed Distribution.
Also Tail=1, then it is calculated as $TDIST=P(X>x)$ , where $X$ is a random variable that follows the T-Distribution.
And Tail=2, then it is calculated as $TDIST=P(X>xorX<-x)$ .
This function will return the result as error

     1. Any one of the argument is non-numeric. 
     2. DegreeOfFreedom<1 and Number<0. When we are giving DegreeOfFreedom and Tail as a decimals, then it is changing in to integers.
