We begin our introduction into probability by discussing the ideas of events in a sample space. We discuss the main formula for computing the probability of an event and the rules for when events are independent. In the following videos we will talk about the multiplication and addition rules, permutations and combination, conditional probability and finally Bayes' Theorem.

I recommend everyone wanting to get a better understanding of probability this guy videos, his explanations, the way he get into the topic is simply fabulous. Clear, step by step evolution on the topic, good real life examples to finally get you understand the the whole picture and also deeper. Thank you very much for those great contents you put here for us.

Thank you so much!

Agree!

You know Professor Bazett, you could probably put a lot of colleges out of business. Poor students like me would have totally poured out our tuition dollars into your videos rather than paying for that subpar product they call a college education. Keep it up!

@amadeus23333 3 года назад

Just wonder why is probability part of discrete mathematics? because of topics like discrete random variable?

@DrTrefor 3 года назад

It is typically first introduced here for discrete random variables, and then continuous variables can be added later. It is useful enough that many students of many disciplines end up connecting with probability in some way or other.

@mariuszwiesiolek5777 6 лет назад

I like your stuff, Trefor, however, could you split your Discrete Mathematics channel into two pieces? It would be easier to find your Probability videos which are absolutely brilliant and enlightening! It was the reason I came here and gave you sub!

@abdullahfaisal4389 3 года назад

As the sets have no impact of repetition of elements acc. to the "set theory", it seems kind a like unfit for sample space. e.g. if i have some distorted die,given that the probability of getting the face marked '3' is twice that of any other face out of other five(equally likely).Then i should have to put and consider the sample point of getting '3' twice in my universe or sample space. Please resolve my confusion!

@youssefdirani 2 года назад

Sample space is what you may get. And you may get 3. So it's just 3. How often you get it is related to its probability not to itself being more than once in the sample space.

@dariuszspiewak5624 2 года назад

No. You don't put a point twice into the set. All elements in a set are unique. There are no repetitions. Ever. What changes in your case is the probability measure for the point. If on your die you've got two 6's, then the probability that you'll roll a 6 is 2 * 1/6. The rest of the points have a probability of being rolled 1/6.

@dariuszspiewak5624 2 года назад

A random variable is a function from a probability space into a measurable space. This is the formal definition.

@youssefdirani 2 года назад

@@dariuszspiewak5624 does every probability value (e.g. 1/6) maps to only one particular value of a random variable ?

@dariuszspiewak5624 2 года назад

@@youssefdirani No. Probability itself is a function (with some special properties) from a sigma-field of events into the interval [0, 1]. Therefore, any certain value in [0, 1] can be the value of the function for many different events.

Well, this is just my two cents (bah dum tsh) but I don’t really think it’s a quarter, otherwise it would be 25 pennies rather than one penny twice(bah dum tsh again)
