Probability and statistics on Khan Academy: We dare you to go through a day in which you never consider or use probability. Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics. In these tutorials, we will cover a range of topics, some which include: independent events, dependent probability, combinatorics, hypothesis testing, descriptive statistics, random variables, probability distributions, regression, and inferential statistics. So buckle up and hop on for a wild ride. We bet you're going to be challenged AND love it!

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 :)

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?

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

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.

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)
