this is what happens when a teacher isn’t constrained by time or syllabus. he’s not rushing to get everything finished in time, he’s able to explain the theory behind it without worrying about finishing a syllabus. so refreshing!

Is anyone else wondering why people "roll" a die? When you "roll" something, its normally spherical, right? But a die is a cube and doesn't really "roll" It, more or less, tumbles.
Interestingly the "tumble" word in relation to dice has been reserved for objects other than hands that are used to shake and then "roll" the dice, called dice tumblers.

3) Bello plays cricket for his school team. Last season they won 5 games, lost 7 and drew 4. a) What was his team’s chance of winning a game last year? He says that this year they have a better chance of winning. He estimates that they should have at least a 40% chance of winning their matches. b) If they play the same number of matches this season, how many would you expect Bello’s team to win? c) Halfway through the season Bello’s team has won 4 games, lost 1 and drawn 3. He adds these values to last years results and calculates a new probability of the team winning. win=9 lose=8 draw=7 What did Bello calculate the new probability to be? d) Bello uses this value to estimate the number of matches he will win in the second half of the season. What value did Bello get?
Tommorow we have the explanation of this lesson, and i feel that i caught it very easily it opens for me new roads for playing chess diy...etc LIKED IT!
Thanks you made this so simple! Just wanted to request if you can make a video on how to predict numbers. Example: 64,16,4,1,__,__. 3,-6,12,-24,__,__. Problems like the two above always stump me on test and quizzes. I would appreciate it if you can explain this your a great teacher!
Ik it's 10 years later but... this is best done finding the common attribute. In the first problem, it's dividing by 4, and the second one, multiplying by -2.
Well done. Probabilities many times are computed based on a data sample, and collecting a sample with high quality data might be the most difficult part.
Independent events were events that fit the constraint (flipping a heads or rolling a 1). Dependent events were the total number of equally likely occurring events (two equal sides on the coin or 6 sides for a die). He actually did explain this, however didn't use words like dependent and independent because they're confusing, and also the reason why most students ended up watching his videos. He simplified the theory that's badly taught in schools so more people can learn.
your voice. It is so much like the voice of a young man I see in videos on Facebook that are usually about how awesome certain animals are. For instance there was one about wolverines... are you the same guy?
Well, I've seen a person land a quarter on the rim. It's very improbable due to bounce, gravity, wind, or vibrations on the surface if whatever you are throwing the coin on. Its density as well, but if the conditions are right. It's probable.
Khan academy is the best at explaining things. At first i had a problem with this lesson but then i saw his video the best and the most simplistic way of explaining Thank you khan academy
For those who are Grade 8 and are Asked to simplify their answers after finding the Probability, It's easy.. Let's me give you an Example. Q1 : A person threw a dice, What is the Probability of getting an Even Number? A Dice has 6 total sides/Numbers, How many even Numbers are there from 1 to 6? 3.. Why? (2,4,6 are even) Which means the answer is : 3 ----- 6 TO Simplify it.. Divide 3 and 6 By 3.. Why? Because they both can be divided by 3. So.. 3 Divided by 3 = 1 ------- 6 Divided by 3 = 2 Final answer : 1 -- 2 And that's how you Simplify. xDD
I love these videos and I'm learning so much but they seem to be out of order, both here and the website. Can anyone point to a listing where the videos are in a correct order where new builds on material already covered? I'm finding that a lot of the videos assume skills which have not been covered in earlier videos.
Thank you!! You are lifesaver… 2moro was my test of probability and I didn’t even know how to solve probability... again, thank you! Thank you so much!!!
Can you do a series on stochastic calculus and Black-Scholes Formula? I know, this is probably not on the top of your to-do list, but maybe in the future some time....
That is 100% correct. There iS SOME chance, for that to happen. Its possibilities are VERY low but there is still a small chance for that to happen. So says the theory of probability.
DBIYBIMWBIU If some give me a 100 billion dollars if I could flip a coin and get 1 million heads or tails in a row, even if they gave me eternal life to do it, it would lose. If they repeated the experiment on every planet in the universe, it still would not happen for even after ten out of ten tails, the probability of the 11th tail in a row would be worse than a heads and the odds would get progressively worst per flip. thus although I know there is still a possibility based on probability; the odds of probability are also repudiating its own law or at least that's how it seems.
Dennis B To have an apreciable chance of getting it you would have to try 10000000000000000.....000(three hundred thousand zeros) times. If you get a computer to do it he would take the age of the universe to do this many tries (and still would not get it done). So as you can see there is nothing wrong with probability theory, is just that we humans find it hard to wrap our minds around really small numbers.

For those who are Grade 8 and are Asked to simplify their answers after finding the Probability,
It's easy..
Let's me give you an Example.
Q1 : A person threw a dice, What is the Probability of getting an Even Number?
A Dice has 6 total sides/Numbers,
How many even Numbers are there from 1 to 6? 3.. Why? (2,4,6 are even)
Which means the answer is :
3
-----
6
TO Simplify it..
Divide 3 and 6 By 3.. Why? Because they both can be divided by 3.
So..
3 Divided by 3 = 1
-------
6 Divided by 3 = 2
Final answer :
1
--
2
And that's how you Simplify. xDD
This is a clear explanation. Thank you.
