# probability_any: Find the probability of any (at least one) event happening In covidprobability: Estimate the Unit-Wide Probability of COVID-19

## Description

For an event that occurs with probability p, this function returns the probability of an occurrence given n repetitions. p is numeric and can be a vector.

## Usage

 `1` ```probability_any(n, p) ```

## Arguments

 `n` The number of times to repeat the event (independent) `p` The individual probability of the event happening

## Details

The probability that any event p occurs with n repetitions is equal to the reciprocal of the probability that p never occurs. The probability that p never occurs with n repetitions is `(1 - p) ^ n`. Thus, the probability that any event p occurs after n repetitions is `1 - ( (1 - p) ^ n )`.

## Value

The probability of an event with the specified probability, after n repetitions

## Examples

 ```1 2 3``` ```probability_any(1, 0.5) probability_any(2, 0.5) probability_any(2, c(0.5, 1/3, 0.25)) ```
