The odds of getting something other than a six are 1 in 6. If you roll the die once, the odds of that happened are 1/6. If you do it twice, the odds of still never getting a six are (1/6)^2. Continuing, if you roll six times, the odds of never getting a six are (1/6)^6. Every other possibility includes at least one six.

Ergo, the odds of rolling at least a single six are 1 - (1/6)^6, or 0.999978566 in 1.

Just do the fucking experiment. Throw the dice 100 times 6 times. You dont always get a six within one row.
So it cant be 100%.
Fuck you.

Psyche I'm tired.

Fixed:
Odds of not getting a six the first time are 5/6.
Odds of never getting a six after six times are (5/6)^6.
Odds of getting at least one six are 1 - (5/6)^6... or 2/3.

Good catch.

I don't care what you roll. I've rolled a dice 6 times in a row and gotten 1's every time before. Where was your 1/6 * 6 then?

If I posted all 100 rolls you'd just bring up some bullshit about me bringing up random numbers so what's the fucking point?

[Anonymous No.1584233]

why don't you simply solve this by experimentation. Everyone roll a 6 sided die 600 times and post how many 6's you rolled. We will then have an answer.

You're the owned one, I did 24 rolls of 600 and got atleast one six every time, prove to me that it won't happen every time

Fun fact: replace 6 with x, and it's 1 - ((1-x)/x)^x. As x approaches infinity, the odds approach ln(2) (about 69%).

rolled six different die at once;

1st time: 5 2 5 1 3 5
2nd time: 2 4 4 4 4 5
3rd time: 2 3 6 1 6 2
4th time: 5 2 2 3 6 6
5th time: 3 2 5 6 6 5
6th time: 6 3 5 2 6 4
7th time: 1 4 2 4 2 1
8th time: 1 3 5 4 3 5
9th time: 4 5 5 6 6 2
10th time: 1 4 6 2 3 3

times with a 6:
times without a 6:
probability of rolling a '6' out of 6 rolls: 6/10 or ~60%

If i did it more, the probability would likely move towards 66%, but it's definately not 100%

[Anonymous No.1584291]

>>1584205
By your experiment:

What are the odds of rolling a one on a six sided dice if you roll six times? 4/6
What are the odds of rolling a two on a six sided dice if you roll six times? 4/6
What are the odds of rolling a three on a six sided dice if you roll six times? 4/6
What are the odds of rolling a four on a six sided dice if you roll six times? 6/6
What are the odds of rolling a five on a six sided dice if you roll six times? 2/6
What are the odds of rolling a six on a six sided dice if you roll six times? 6/6

Can you explain why the odds change number by number?

[Anonymous No.1584296]

take the odds of it not happening(5/6), raise it by the number of occurrences (6), and subtract that number from 1, it's not that hard..

forgot to type in the numbers. Whoops.

[Anonymous No.1584318]

>>1584291

Because the number is higher, it's chance of occurrence increases, this is also why it's more likely to roll a 7 with 2 dices than it is to roll a 2

What was your point again?

[Anonymous No.1584385]

>>1584205
Lets change the question and let the roll be 3 instead of 6. Since the chance of rolling a 3 is the same as a 6. Look at your first 6 rolls there are no 3's.

[Anonymous No.1584392]

>>1584385

I already explained this,
see >>1584318

[Anonymous No.1584393]

I rolled a 6 sided die and got 6, therefor I conclude that the chances of getting 6 from from rolling a six sided die is 100%. Extrapolate that and the chance of getting a 6 if you roll 6 times is 600%.

TL;DR the answer is 600%, tested IRL so it must be a fundamental truth of the universe.
