0:37 S.D. is $25.05, not $28.01. If you are right then plz explain how?

Yes, the population standard deviation is 25.05. In the video it assumes that the 5 wallets are a sample of the general population so it uses the sample formula for standard deviation which divides by n-1 rather than n. Apologies, this could be made more clear in the video.

The day after the election fraud of 2019, this statistical truism more than 40 years since I completed the college statistics course returned to my recollection. I just heard this guy refer to the term bias, indeed bias = fraud when the counting involves an election. ANYONE, who had the same course I had knows, and would see the same fraud I seem, One only needs good sense to see the obvious. This is simple, it doesn't require a knowledge of statistics. This regime we live under, not just the regime the entire system is corrupt to include the courts. The greatest single thing they fear, and hate is the TRUTH. WE are sheeple, God Almighty help us..

At 3:46 shouldn't the formula be P(A or B) = P(A) + P(B) - P(A and B)?

I've seen some places when calculating the mean of the squared differences, they divide them by 1 less than the amount. So for your example, it would be... 9+4+1+4+16 / 4 = 8.5 = 2.9 Why would they do that?

3:17 you said the last door the host left for you. But what if he left you a goat? Its still equal. Your only focused on probability of winning and not probability of losing. The host that opened 98 doors didnt leave you the car, he left you a choice. And the choice is still 50/50 If he left you the car then switching is good. But who knows if he left you a car or left you a goat When he opened 98 doors Your 1% chance goes up to 50%. Not 1% to 99%

Assume you stay with your first pick. If your first pick is Goat A, you get Goat A. If your first pick is Goat B, you get Goat B. If your first pick is the car, you get the car. You only win 1 out of 3 games if you stay with your first pick. It's just basic math/logic kids understand.

Dude, look at the image that has 3 doors and a car behind a door. Doesn't matter which door the car is behind. This is a graphic that illustrates the 1/3 probability of where the car is. It is also the 1/3 probability of ALL that can occur. Either the car is behind Doors A, B or C, each image represents 1/3 of the time what can happen. So together these 3 images represent all the possible scenarios that exist before you make the pick. Now for some reason, these cult members suddenly decide they don't know what each image actually means. It actually means 1/3 of the time, the car can appear behind a door. But here's the important part; it also means 1/3 of the time, the car will not be behind BOTH the other TWO doors. Not 2/3 of the time the car won't be behind the other two doors; it is 1/3 of the time. These guys see 1/3 of something and 2/3 must be ANYTHING else. What does all this mean? It means each car door has the value of 1/3. Each goat door has a value of 1/6. Once you see this, you'll understand where they've made the mistake. It's quite simple, isn't it? Bottom line - Monty Hall Paradox is a 50/50 GUESS to stay or switch for the car. You're welcome.

You only win 1 out of 3 games if you stay with your first pick. Switching means the opposite. It's just basic math/logic kids understand. Sadly, it's far too hard for idiots.

@@TristanSimondsen "You and 2 friends have a chance to win a car. One of your friends drops out of the contest. What’s the probability of you winning the car? Should you always say your friend has the higher probability because 2 is better than 1?!?" lmfao at your stupidity. Your stupid friend, that drops out, had a winning chance. The door that the host remove, never has a winning chance. Let's say that a few second later, your friend decide to return to the game. He has a 1/3 winning chance, right? Let's say that a few second later after Monty Hall open a goat door, he close that door. Does that door has a 1/3 winning chance?
