# TDIST

Calculates the probability for Student's t-distribution with a given input (x).

### Sample Usage

`TDIST(A2, 30, 1)`

`TDIST(0.5, 1, 2)`

### Syntax

`TDIST(x, degrees_freedom, tails)`

• `x` - The input to the t-distribution function.
• `degrees_freedom` - The number of degrees of freedom.
• `tails` - Specifies whether the calculated distribution will be one- or two-sided. (1 for one-tailed distributions, 2 for two-tailed distributions).

`NOMDIST`: The NORMDIST function returns the value of the normal distribution function (or normal cumulative distribution function) for a specified value, mean, and standard deviation.
`BINOMDIST`: Calculates the probability of drawing a certain number of successes (or a maximum number of successes) in a certain number of tries given a population of a certain size containing a certain number of successes, with replacement of draws.
`EXPONDIST`: Returns the value of the exponential distribution function with a specified lambda at a specified value.
`NEGBINOMDIST`: Calculates the probability of drawing a certain number of failures before a certain number of successes given a probability of success in independent trials.
`PROB`: Given a set of values and corresponding probabilities, calculates the probability that a value chosen at random falls between two limits.
