Calculates the probability that all probabilities happened simultaneously.
`independent_probabilities()`

just multiply the probabilities of the index
passed.

## Usage

```
multiply_probabilities(p, i)
independent_probabilities(p, i)
```

## Arguments

- p
Numeric vector of probabilities.

- i
Numeric integer index of the complementary probability.

## Value

A numeric value of the probability.

## Examples

```
multiply_probabilities(c(0.5, 0.1, 0.3, 0.5, 0.25, 0.23), c(1, 3))
#> [1] 0.03898125
independent_probabilities(c(0.5, 0.1, 0.3, 0.5, 0.25, 0.23), c(1, 3))
#> [1] 0.15
