**The number of successes in n independent Bernoulli trials has a binomial distribution.**

n independent Bernoulli trials

- There are n independent trials
- Each trial can result in one of two possible outcomes, labelled success and failure.
- success can be a bad thing – tire blow-up.

- P(success) = p,
- P(failure) = 1-p

A balanced dice is rolled 3 times. What is probability a 5 comes up exactly twice?

p = 1/6

n = 3

x = 2
