Binomial Probabilities

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)`
```

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)`
```
