Lesson 2: Theoretical & empirical probability distributions

# Theoretical probability distribution example: tables

We can create the probability distribution for rolling two dice by creating a table to represent the events that make up the sample space. Created by Sal Khan.

## Want to join the conversation?

• is there a logically simplified way to create a probability distribution?
• Making a small table as shown in the video is already the simplest way there is, and it's a way recognized by collegeboard as well. The more complicated option will be a bar graph.
• The question is not as clear as it could be. I would think that if you said the absolute value of the 2 dice would be more clear.
• Is it possible for a 3-sided dice to exist in 3 dimensional world?

I mean not a more than 3-sided dice with 3 numbers on some of the sides but a physical dice only with 3 sides each of which has 1, 2, or 3 signs on it.

All I could come up with is to make a 2-dimensional right triangle with 1, 2, or 3 sign on each angle, to pin it on a wall, and to spin them like a roulette. Then to wait for a while and read the number with the smallest angle to me.

I know it's not a dice and there's an edge case like two angles toward me with the same angle, giving no definite answer. So please help me to play with A real 3-sided dice for real.
