I am trying to generate a random integer that follows this distribution.

$$ P(X=k)=p(1-p)^{k-1}$$

for

$$ k=1,2,…$$

I tried to use sample with some numbers, but i do not know how to use the distribution.

## Best Answer

This is the probability mass function of the geometric distribution.

If you use R: To sample from the geometric distribution, first specify the probability $p$ and then use the

`rgeom`

function:
