### Observed probability, classical probability, subjective probability

8

## What is observed probability?

### Refers to the probability of events that already happened.

9

## What is classical probability?

### What should happen based on each simple event having an equal chance of occurring.

10

## What is subjective probability?

### Probability estimate based on an educated guess.

11

## What are two features of probability?

### A probability is always positive and between zero and one.

12

## What is the law of large numbers?

### The more observations made, the closer you can get to classical probability.
