Probability Theory

## Multiply probabilities

Sometimes it is impossible to pick one event, hence, we should refer to the **multiplication rule** for independent events.

**Independent events** mean that the occurrence of one event doesn't depend on another event like flipping two coins or rolling two dies.

Let's talk about the **multiplication rule**.

**Where can I use it?**

In a situation where we certainly know that we are interested in more than one event.

**Example:**

Imagine rolling two dice; calculate the probability that the multiplication of numbers on the edge of two dice is `36`

. The first one has `6`

on its dice **and** the second one has `6`

on its dice.

**Explanation:**

**Here is the formula:**

**Explanation:**

If we want to receive success for both the first and second events, we should multiply the probability of getting a win in the first event and the second. The key for the multiplication rule is **and**. If you see the phrase **the first and the second event** you should use the multiplication rule.
