Probability Theory

## Binomial Probability 1/2

Think about the Bernoulli trial. We have experimented with five coins, but only once. As we want to work with data, it is crucial we understand experimenting once can be a little bit irrational; maybe we were tossing a coin on the street, and the wind became an obstacle, so it is essentially important to have several tries.

As you remember the definition for the **Bernoulli trial** it is time to move on to **Binomial probability**.

It is when we have a defined number of successful trials among all attempts in an experiment with two outcomes.

**Example:**

Tossing five coins three times. Event **"Tossing a coin"** has only two outcomes: head or tail.
