called the Math Missus.
Her real name is Sarah Smellie - honest, that's her name - and she does little math thingies for the great YouTube unwashed. The linked video goes though a couple of math (and physics) problems related to The Price is Right and Let's Make a Deal.
The LMAD segment is just another rehash of the Monty Hall problem, and I've had enough of those. But the TPiR bit is more enjoyable. Sarah sets up a small version of the Plinko board and drops a bunch of ping pong balls down the center chute. This turns out to be the best way to win the ten grand, but also the best way to win $0. Moral of the story: high reward involves high risk.
Sarah doesn't mention another thing about her experiment because the math would get too involved. But the resulting distribution of the ping pong balls in the various slots looks alarmingly like a Gaussian normal distribution curve. Sure, the small sample size knocks the curve a little off-center. But all you Gauss fans - and I know you're out there - will get a small smile.
