Here I thought I was going to get some crazy advantage in board games but I already knew this one. The gaming store I go to has a challenge every Friday night and they play a game and the winner gets a $5 gift certificate. One Friday they brought out a cup of dice and they explained that they were going to roll the dice in the first person to guess what number was rolled correctly was the winner. They recorded everyone's guess in order and someone else counted what the dice rolls was. I literally counted the number of dice and multiplied it by 3.5 and I was spot on. lol

As a professional Dungeon Master, this phenomenon in probability, called the Bell Curve, is really important and useful when fine-tuning dice rolls for weapons, spells, rollable tables etc. etc. For comparison: the classic method to get your ability scores is to roll 4d6 and ignoring the lowest number. This should give you a range of 3-18 in which 10-11 are the highest probabilities. The way I do it in my games is by rolling 1d12+6, which gives a different range (7-18), but with every result being just as likely. This avoids 2 things: characters with a stat below 7 (which is already bad) and characters with stats that are "too flat" (in a full array of 6 abilities, getting 9, 10, 10, 11, 12, 13 is considered very flat). It also shows that the difference between a greatsword (2d6 dmg) and a greataxe (1d12 dmg) is not just that the minimum damage on a sword is 2, but that the sword hits much more consistently, which goes to show that it`s a more maneuverable and precise weapon, while the axe is more likely to get a 12, but also just as likely to get a 1.

Worth mentioning that there are 6 ways to roll a 7 with 2 dice (5+2 and 2+5 are 2 separate outcomes). The video implies that the likelihood of getting a 7 is 3 times that of getting a 12, but its actually 6 times the likelihood.

I was literally just explaining this to a student in my statistics class yesterday! But you did much better 🤦‍♂️

Also like how he subtly mentions that he dropped those first 10 dice several times to get 35. Something to remember for the next time you see something really extraordinary in a video: you don't know how many takes it took to get it right. Not a knock on the Action Lab, I think it's great that he's demonstrating the principle.

Yeah. There is a reason why 7 is the number for the robber.

I thought it was gonna be about how you throw it and then get the number you want..but this is still amazing

I sort of knew this from D&D crpgs, but didn't know how extreme it was. you think of 10d6 as being 10-60 damage, but yeah, maybe it's better to think of it as "around 35 damage".

The more dice you have, the closer you'll get to the prediction as a percentage of the value. But also, the more integers there are in that range near the center value. If I only roll 1 die, I'll get it within 3 every time and I'll get it exactly right 1/6 times. Not true for 100 dice.

my friend and i experienced quite a few amazing/awkward statistic anomalies while playing backgammon: the top one would be rolling the dice for determining who starts the game: we got the same dice 4 times, each time we had doubles.

This "knowledge" hited me when I was learning to play "The Game of Ur". You play with 4 "dices" that have an equal chance each on getting a 1 or a 0, then you sum up all of them and then move your piece. When I realized that the "most probable number" to get is a "2" and you make your moves believing you will most probably get a 2 on the next round, ohh boy, that improved my game ALOT!!

To do this for dice with different numbers of sides, the average fo any one die is (highest value + 1) / 2. So 3.5 for six sides, 5.5 for ten, 11.5 for a d20, etc. To find the most common result for 2 or more dice, multiply the 1 die average by the number of dice. If it's a fractional result, the 2 adjacent numbers are tied for most common. So 7 for two d6's, 10 or 11 for three, 14 for four, 17 or 18 for 5, and so on. Doesn't work for a single die since all sides are equally common.

Your videos are always time well spent!

Simply wonderful! Love it.

Nice video, though, statistically, you would have 6 options to get 7, 1-6 2-5 3-4 But also 6-1 5-2 4-3 Due to this, the chance of getting 7 as sum is 6x as high as getting 12, since 6-6 can only appear once: each die has a six, so the chance is 1/6×1/6=1/36.

just the most easy to listen to person I hope you keep rolling out videos

You videos are always great and informative.

This is why 7 is the thief in Catan. Evens out your chances of getting anything else, with greatest chances being 6/8, 5/9, 4/10, 3/11, & 2/12 in order of most likely. Always put your pieces on 6/8, for those that play, but struggle with statistics.

There actually is a chance to get a sum of 100 or 600 when you roll 100 dice. It's just incredibly small because all the dice would have to land on 1 or all on 6.

This is one of the most useful videos of ever watched. Thanks 😊

This is the same reason a coin falling through a pachinko machine will usually land under the starting position. For each peg the coin can fall left or right, so for two peg layers it can fall LL for left, RR for right, and either LR or RL for middle. So there’s a 50% chance it lands in the middle, but only a 25% chance each for the left or right.

on my way to the casino rn

Now try that with D20s

Can you please do a follow up video on how dice can model entropy, macro vs microstates? Thanks.

This is just a refresher course for D&D players.

I'm pretty sure I have more of a 75% chance of getting the starting side with a coin flip. I can easily get a 12 heads streak just by starting with heads up. I actually ruined a probability experiment back in highschool because of this.

I was about to send this to my roleplaying friends that are subbed to critical failures, until I realised, that it wouldn't work with a single D20 xD Roleplayers would naturally come to know this "rule", since we sum up dice values to get the average quite often (for exemple, when you need to roll 12d10 to find the health of a monster... Either you do it, either you take the average.

Before I see you predict your number, I'm guessing it's going to be thirty-five. That's the most likely of all outcomes. EDIT: Yup. Actually, one thing I wouldn't mind learning is how to figure out the odds of getting the more likely outcome.

dream would get 600 10 times in a row

If you play Settlers of Catan, each of the number markers you place on the resource hexes at the beginning has one or more dots on the bottom. The number of dots directly correlates to the probability of that roll occurring. For instance, 6 and 8 have five dots each, which means there is a 5:36 chance of rolling either of those numbers. Likewise, 11 and 3 have two dots, meaning a 2:36 chance.

I studied this in game design class because in pen and paper RPGs like Dungeons and Dragons, you can choose for instance a greataxe, which has a 1d12 damage, or a greatsword, which has 2d6. Besides the fact that the minimum damage on the sword is 2 instead of the axe's 1, you should choose the sword if you want to deal more average damage, whereas with the axe you can deal maximum damage (12) more consistently, but also minimum damage. The probability to roll of any number from 1 to 12 is exactly the same
