geometric distribution

how many times do you have to do the trial to get at least one success


  • \(p\) is the probability of one individual success
  • \(x\) is the number of trials


\begin{equation} P(X = x) = \qty(1-p)^{x-1} p \end{equation}

which represents the probability of getting a success on the \(x\) trial
