# LOGNORMDIST

### Definition of LOGNORMDIST

Returns the value of the log-normal cumulative distribution with given mean and standard deviation at a specified value.

### Sample Usage

`LOGNORMDIST(4,4,6)`

`LOGNORMDIST(A2,A3,A4)`

### Syntax

`LOGNORMDIST(x, mean, standard_deviation)`

`x`

- The input to the log-normal cumulative distribution function.`mean`

- The mean (mu) of the log-normal cumulative distribution function.`standard_deviation`

- The standard deviation (sigma) of the log-normal cumulative distribution function.

### Notes

- A log-normal distribution function is a probability distribution function of a random variable whose logarithm is normally distributed.
