ODDS

(5/6)^9 = 0.194

That is the probability .^

If P=a/b then odds against are (b-a)/a.
EG P= 1/3 odds against = (3-1)/1

I make it odds of 9/5 in my head

odds against 4 appearing with 1 dice are 5/1, therefore with 9 dice 5/9

therefore odds AGAINST must be 9/5, shirley!

I ask as im am going to the casino on sunday and am doing the 6 line and if I win only once in 9 goes I will be up. so I was thinking what Is the chance  of winning or losing in this scenario?

I should let you know its single zero roulette

kenny, you`re adding the probabilities, rather than multiplying them. If you have a 5/6 and 5/6 double, you don`t get paid at 10/6.
With six dice thrown on average there should be one `four` with every throw. With more than six dice thrown, you will be getting more than one four, on average, meaning a four is more likely to appear than not to appear, making it a mathematical odds-on shot. So, it can`t be 9/5. Andriy has it right, rounded to 1.2 or 1/5

thanks timbuctooth I thought the other answers looked a little wrong

Incidentally there is no difference in these odds for one die thrown 9 times and 9 dice thrown simultaneously.

1.166666666666 x 9 equates to almost exactly 3/1

1.16 x 9 = 10.44

What has that got to do with OP's question?

Andriy is correct

0.194 = 4.15/1

Andriy did do a sum correctly, but didn't answer the question correctly.  Pumphol didn't even do his bizarre sum correctly.  You are the first person to actually answer the question.

The odds are 104/25 and the probability is (5/6)^9.

Well I was doing 1.166 x 1.166 ( 9 times ) to get the 3/1
Now that may be the wrong formula  & even wrong answer  but I would have thought you would have at least seen where I was going with the 1.16 & 9 ( the nine equating to nine dice or nine throws ) so the 1.16 x 9  equating to 10.44 is not what I meant especially when I said I made it around 3/1,

My formula or lack of it was wrong but you wrote 10.44 not me, but thanks anyway for being so condescending.

so is it more or less than 80% chance a 4 would not come up = about 5-1   ?

No, it's a 19.38% chance that a 4 will not come up

0.833333⁹ = 0.833333×0.833333×0.833333×0.833333×0.833333×0.833333×0.833333×0.8333... = 0.19380600176481308

yvw

thanks evee that sounds like 80% a 4 would come up { is that 4-1 or 5-1

4.15/1

Surely that`s ^^^ NOT to come up?

Getting ridiculous. Are you taking the p.ss AM?
Yes, 4.15/1 that a 4 will NOT come up.

ha ha ha ha

thanks eeve. seams like about 4.15ish - 1. correct?

?

'Ow did you get on that day back in April at the casino, AM?

ist like poker, you have 54 numbers 9 number 4 so take the 9 from the 54 =45/9hence 5/1
