LESSON: Intro to Probability Notation
Probability Notation
This quarter we are going to be focussing our studies on Probability! What is probability you ask? It's simply how likely something is to happen. If we're unsure about the outcome of an event -- whether it be the outcome of a basketball game, flipping a coin, willing the lottery or passing your statistics class -- we can talk about the probabilities of certain outcomes and how likely they are. The analysis of probabilities is called statistics. That's why we learn about probability in a statistics course.Before we jump in to learning about probability, it's important that you become very comfortable with the notation that will be used. It looks different than what you're used to. And if you're not paying attention now, it will definitely look like a different language down the road.
In this lesson video you will see a basic probability example of drawing poker chips out of a bag. You will also see the proper notation to denote probabilities and be introduced to the operators $$\bigcup$$ (or), $$\bigcap$$ (and) and | (given).
