1 in 3? Or have I just made myself look stupid...
Now i'm thinking of several ways that could be right or wrong and i've confused myself on a question about a simple dice roll.
Clearly I'm not the target audience here |

"1 in 6, then one in 5. Unless you get 'it' on the first go then your odds are 1 in 1. Maybe."
I wasn't very clear.
I've got 5 dice, 4 of which are the ones I need and the other one I can roll twice in order to get the one outcome that I need.
So it's 1 in 6 on the first roll and 1 in 6 on the second, but what would it be if I were to ask what are my chances of rolling a 1 (the only positive outcome) when I have two attempts. (If I rolled a 2 on the first roll, I could still roll a 2 on the second roll too) |

Hah, how'd you get to that?
To be fair, staying up til 2am turns any question into a brain teaser. I've got 2-3 different answers to this one simple question and... yeah, it's probably bedtime |

It's 1 in 6 every time you roll a die..
The odds won't change because of the outcome of rolling any number on any amount of other dice
I must be good at odds as I'm up £1750 on live Casino on the net..
Just luck nowt else |

OK... so you're rolling one dice, with 6 sides and have 2 chances to roll it, and you only want 1 particular outcome?
The first roll, and presuming you don't get what you want first roll, it seems like you have a 2 in 12 chance?
Ugh maths, i like puzzles though.

Could it be 1 in 12 on the first roll and 1 in 6 on the second?
2 in 12 is the same as 1 in 6 isn't it? |

No. Like the guy above said the odds of rolling something one one particular dice is always the same. There are always 6 sides on that dice and always a 1 in 6 chance to get 1 outcome.
2 in 12 is just the raw answer. You're rolling 1 dice 2 times. So you have a 2 in 12 chance but usually you make fractions the smallest version of themselves and the smallest version of 2 in 12 is 1 in 6 again. |

Nothing new
Just because I pick up the thinking slack of the world from people like you who just can't manage on their own "
It's 6 to 1 no matter how many times you try. For the odds to change you'd have to take a number away each time you try. Derrrrr |

Yes correct - 2 in 12 chances -
the "odds" are still 1 in 6
Divide 2 into 12 = 6:1
Like 4 in 16 chances is 1 in 4 or 4:1

1 in 6 is the odds for each roll. I want the odds for the total amount of rolls. I don't even know if that calculation is possible.. |

Apparently it's this
1:6 [first roll] + (5:6)[probability of first roll not being a 1] x(1:6) [probability of second roll being a 1] = 11/36
It sounds clever. And it work out at just under 1 in 3.
I don't know though. I need a maths professor or something! |

Same as a roulette table .. if the marble lands on black 12 times in a row, what are the odds of it landing on red next time?
The odds are exactly the same as it will land on black because each spin is an individual occurrence and the dice is the same. Each roll is a new even so you will always have a 1 in 6 chance of getting the desired outcome and the amount of rolls you make is irrelevant.
I think! |

So the second roll is irrelevant unless the first one fails? |

You can only ever have a 1 in 6 chance of rolling what you want, seeing as there's 6 numbers. Every time you roll one dice you always have a 1 in 6 chance.
Took me about a year to understand the Monty hall puzzle tbh as it didn't make sense to me for a long time.
The probability of something happening is always 1 or 0.
In your example of rolling 1 dice twice this means you only use addition to work out the probability. Maybe think of it this way..you are rolling the dice once, then roll it an additional time, so you can add the probability (like i did with 2 in 12).
I'm a shit teacher but it's my favourite role play. |

If you don't need to roll the dice twice then you rolled the first dice once, which is a 1 in 6 chance. There's no more than one dice and no more than 6 sides.
Probability laws don't change unless some variable makes it more complicated (like 2 dices being rolled at once and you want 2 different numbers). They aren't really 'maths', they're more predictions and they don't even have to correlate with actual data/results. |

The odds should still be 2/1
There are only 6 possible outcomes and 4 of them are unfavorable and 2 favourable 4/2 which when broke down to the lowest common denominator gives 2/1 |

I always though you just timed the odds. So rolling a two 1s consecutively would by 1 in six times one in six, so 1 in 36. As there are 36 possibilities when rolling a die twice. That's what I was taught at school, but seemingly everything that is taught at school is wrong in some way |
