tbh I realized why we are learning stuff at school even though we have loads of that stuff on the net. the thing is, if we don't learn some things by heart, meaning so that we can immediately access the information from our brain, we will always have to search things online, through books, ask others, etc. anyways, my point is: if those people from the past didn't know certain information, they wouldn't be able to quickly draw conclusions from there if that makes sense. like if u know something, then you skip it and move on. but if u have a gigantic problem in front of u and u can't break it down into smaller, easier, and more achievable tasks, ur fcked :)

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.
Thanks! I'm going to have to do this tomorrow at school but I had no idea what probability was but this video helped me a ton! I now understand it and it's actually really easy.

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?
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.
Even we're learning everything in French and Arabic there is a high probability the government will switch to english soon. i love your courses not just probability but also micro/acroeconomics math.... Thank you so mutch frome Morocco.
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?
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
Wow!!! I am in 9th grade... Since 6th grade I never understood proablity and I lost interest... Not even math antics can help me.... But you did pretty good and now I recognize How easy proablity is.... All my math teacher's mistake....😁😊
one thing is that, heads and tails are not exacly 50/50. According to standford research, it is known that it is 49/51, this is where 51 is for the side the coin is faced upward.
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.
Bit of an abrupt ending but a very helpful video I was doing my nwea and it was getting on my nerves that I had like 5 probability questions and I had to guess but it turns out the equation I was using, (even though it wasn't this precise equation, it) was correct and this video was super simple to understand. Thank you. (Still need to work on your outro tho)
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.
I'm looking at videos on this subject because my online math class is too boring and I got test tomorrow and the day after. Wish me luck because I'm gonna wing it with basic understanding and zero practice.
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.

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
