## Description

To use R in a Sage cell, the language must be set to R. See https://github.com/sagemath/sagecell/blob/master/doc/embedding.rst for details.

Here, we will calculate the probability of 2 successes in a binomial distribution of 10 trials with a probability of success of .05 using the `dbinom` command

## Sage Cell

#### Code

`dbinom(x=2, size=10, prob=0.05)`

## Options

#### Cumulative Probabilities

Using the `pbinom` command we can calculate the probability of any one of a set of successes. Given `q` successes in `n` trials, we may calculate the probability of `q` or fewer successes by setting `lower.tail` to `TRUE` or `q` or more successes by setting `lower.tail` to `FALSE`. The default value of `lower.tail` is `TRUE`

#### Code

`pbinom(q=2, size=10, prob=0.30, lower.tail=TRUE)`

`pbinom(q=4, size=10, prob=0.30, lower.tail=FALSE)`
