### Transform > Probability Distributions > Geometric

Calculates probabilities, cumulative probabilities, and inverse cumulative probabilities for a Geometric distribution.

The Geometric distribution is the probability distribution of the number of failures before the first success. It is supported on the set {0, 1, 2, 3,...}

### Dialog box items

•Statistics:

Choose from the following options:

oProbability density: Choose to calculate the probability densities.

oCumulative probability: Choose to compute the cumulative probabilities.

oInverse cumulative probability: Choose to compute the inverse of the cumulative probabilities.

•Distribution: Select the distribution for the variable.

•Prob of success: The probability of success. Must be greater than zero and less than or equal to one
