And that’s the 3. So if I were to ask you, what is the probability given that I’m rolling a fair die– so the experiment is rolling this fair die, what is the probability of getting a 1? So one way to think about it, and this is the way that probability tends to be introduced in textbooks, is you say, well, look, how many different, equally likely possibilities are there? So that’s the 1. You know, you normally think an experiment is doing something in chemistry or physics or all the rest. And I could write that like this– the probability of getting heads. Now, let’s do another very typical example when you first learn probability.

So one way to think about it, and this is the way that probability tends to be introduced in textbooks, is you say, well, look, how many different, equally likely possibilities are there? I could roll a 1 or I could roll a 6. Well, in any roll of the die, I can only get a 2 or a 3. And that’s the 3. And so if I were to ask you, what is the probability– I’m going to flip a coin.

So if I were to ask you, what is the probability given that I’m rolling a fair die– so the experiment is rolling this fair die, what is the probability of getting a 1?

Random number list to run experiment. In this case, it was heads.

We’re assuming that mstering lands flat. So here’s my die right over here. And of course, you have, you know, the different sides of the die.

Intro to theoretical probability

So now there are two possibilities that meet my constraints, my conditions. And I want to know what is the probability of getting heads. Now, what is the probability– and this might seem a little silly to even ask this question, but I’ll ask it just to make it clear.

And this is the idea of rolling a die. Intro to theoretical probability. Well, 2 is even, 4 is even, and 6 is even. And there’s always some chance– even if you flipped a coin a million times, there’s some super-duper small chance that you would get chrmistry tails.

If you’re seeing this message, it means we’re having trouble loading external resources on our website. And how many of those meet my conditions?

So this would be the heads I guess. So there’s two possibilities here, two equally likely possibilities. And it’s actually a fun thing to do.

Interpreting results of simulations. So 3 of the possibilities meet my conditions, meet my constraints. None of these are 2 and a 3.

So in the case of the probability of figuring out heads, what is the number of equally likely possibilities? Try to draw George Washington.

Random numbers for experimental probability. And the other side, of course, is the tails. So one way to think about probability is if I were to do this experiment, an experiment many, many, many times– if I were to do it 1, times or a million times or a billion times or a trillion times– and the more the better– what percentage of those would give me what I chemishry about?

Video transcript What I want to do in this video is give you at least a basic overview of probability. So in this situation, there’s six possibilities, but none of these possibilities are 2 and a 3. Well, only one of them meets my condition, that right there.

They cannot happen at the same time. Chejistry no way to roll this normal die and all of a sudden, you get a 2 and a 3, in fact. But an experiment is every time you do, you run this random event.

Getting a 2 and a 3 are mutually exclusive events.
