Kevin answers a series of, "Things that make ya go hmmm...?" questions with a blend of physical images and computer graphics. Why did humans start eating cheese?

9. Should You Switch? No! (Here's why)
September 23, 2020
In The Two Envelopes Paradox -- also called the Exchange Paradox -- you know what the right answer is almost immediately. Until you don't. And then you do. And then you're not sure. The problem isn't so much the problem itself; it's figuring out why the setup is wrong.

8. This Is Not 50/50
September 23, 2020
The easiest fair games depend on equal, binary outcomes like flipping a coin or drawing a playing card that can only be either red or black. If a game depends on both players choosing an equally-probable outcome, how can one player have a massive advantage over the other?

The Missing Dollar Riddle
6. The Missing Dollar Riddle
September 23, 2020
Kevin explores the math and mystery behind a classic riddle that just... doesn't make sense. Three friends go out to lunch and split a $30 bill evenly. Each pays ten bucks.

A Problem You'll Never Solve
5. A Problem You'll Never Solve
September 23, 2020
Newcomb's Paradox has confounded philosophers, mathematicians, and game players for over 50 years. The problem is simple: You can take Box A, which contains $1,000, *and* Box B, which contains either $0 or $1,000,000, or you can just take Box B. The right choice seems obvious -- but there's a catch.
The Dice Problem Newton Got Wrong
4. The Dice Problem Newton Got Wrong
September 23, 2020
The Newton-Pepys Problem represents Isaac Newton's only documented foray into probability. Samuel Pepys sent him a letter asking whether it would be more likely to roll one six in 6 dice, two sixes in 12 dice, or three sixes in 18 dice. In terms of computing the answer, we've got it pretty easy. But Newton had to work it all out himself, and as he did that but he missed a few things.
The Martingale Problem
3. The Martingale Problem
September 23, 2020
The Martingale Betting system claims that by doubling your wager after each loss, no matter how many times they lose in a row, a gambler is guaranteed to eventually win big. It's considered foolproof, and mathematically it is... until it isn't. With the aid of a faithful blackjack-dealing robot friend, Kevin puts this 18th-century France gambling strategy to the test.
MrBeast's $1,000,000 Dilemma

Let's say, hypothetically, that famous YouTuber Mr. Beast created a free $1,000,000 contest in which anyone could play, but the only chance for a winner is if one and only one person entered. What would you do? Would you enter and hope you were the only one? Would you enter just to destroy another person's chances? Or would you not bother at all?
The Nugget Algorithm
1. The Nugget Algorithm
September 23, 2020
The Frobenius Number -- also called the McNugget Number -- is the highest number you *can't* make out of two integers that have a greatest common divisor of 1. This late 19th-century math quirk was examined by Ferdinand Frobenius and expanded on by JJ Sylvester, but it came to public consciousness by examining the impossible orders of McNuggets in the United Kingdom.
