Post your answer(s) with your Rollin account. Rollin account should be at least level 2 OR the bitcointalk account full member and above.
First to answer correctly, to the point wins the prize.

Remember, no edits.

Ah, sorry.. the question is

Whose chance of losing went up?..

fixed it.

I'll simplify the names and sorry none of the answers is the expected answer.

Looks like the question is not correct in the first place lol. Grin

Anyway, the expected answer is not 1/2 : 1/2. Well, the question contradicts itself more than once, I will replace it with another question.

Edit: I couldn't find a winner. Sad

It is pretty complicated and some answers ignore the part of dice entirely or that Max has only 50% of the chance that Sax has.

This is an example of Bertrand's box paradox
https://en.wikipedia.org/wiki/Bertrand%27s_box_paradox

Bertrand's box paradox is a classic paradox of elementary probability theory. It was first posed by Joseph Bertrand in his Calcul des probabilités, published in 1889.

There are three boxes:

a box containing two gold coins,
a box containing two silver coins,
a box containing one gold coin and a silver coin.
After choosing a box at random and withdrawing one coin at random, if that happens to be a gold coin, it may seem that the probability that the remaining coin is gold is 1⁄2; in fact, the probability is actually 2⁄3.

You can read the explanation for the solution here : https://en.wikipedia.org/wiki/Bertrand%27s_box_paradox#Box_version

Simply stated, the Bitcoin you picked could be of either Box 1 or Box 3. There is thus 2/3 chance that Box 1 is the box picked and 1/3 that Box 3 is the one picked. Therefore, there is 2/3 chance that the other one is also a Bitcoin.

The probability is 2/3....

Well, arguing that 66.667% is not equal to 2/3, you win 1 mBTC

Quote

in fact the thing that you pick a BTC coin don't change probability of the choose of the box.
If for example we have:
Box 1: BTC 1 -btc2
Box 2: ltc 1 -ltc 2
Box 3: BTC 3 - ltc 3

The extracted BTC could be only one of BTC 1, btc 2, BTC 3, so possible cases for the BTC are 3/3.
If I pick one of 3, the P is now 2/3.

That is correct. But the last part is a bit vague, but your approach (the beginning) is correct.

You win 2 mBTC

I'm going to go with my math-gut-feeling

The probability is 66.667%

Yes, the correct answer is 2/3 Cheesy

You win 2 mBTC

You know for sure you don't have the box with 2 litecoins.
That leaves two options:
1. you have the box with 2 bitcoins
2. you have the box with 1 bitcoin and 1 litecoin
Before getting a coin out of these 2 boxes, there is a 75% chance to get a bitcoin, and 25% chance to get a litecoin. You got a bitcoin already, which makes it more likely you have the bitcoin-box than the bitcoin/litecoin-box.

You have said that there is 3/4 chance of picking a bitcoin and 1/4 of picking a litecoin once you remove the other box and that it is more likely to have the bitcoin-box than the bitcoin/litecoin box, but how likely?

You win 1 mBTC. Grin

I have no idea what this classic bitcoin and litecoin problem is called Cheesy

Things are happening at Rollin Chatter box and you are invited.

Sorry to hear that mate, I was watching some of your bets and as I saw you were good at first but seems that you are a bit greedy then you lost your money as a usual story of gambling "greediness takes all your money" Grin

Nah, not greedy. I was aiming for 0.008BTC profit, then just to breakeven. It went on a bad streak.. when I got on a good streak I didn't have much to spare lol, and then it turned bad again and I stopped. I didn't lose all my balance, but I lost most.

Is there a 100% rebate on loss for those who top the leaderboard? Grin

Quote from: Bitinity on December 11, 2015, 08:47:12 AM

Damn that's a big amount, did you lose it on single bet or some bets? Hope you can recover your lost next time.

No, really I am not likely to bet like that again.

hello , I recently tried ur gambling website.
can you explain about affiliate?
I do not understand the system , when payments and where I can get the result. of each total wagered from my referal?
thanks before Wink

you will get your commision instantly after your referrals have made a bet, you can check it on the refs stats page

so, if my refs bet 1 bitcoin x 20% comission. i can earn 0.2 right?

House edge of 1BTC bet = 0.01
20% of that = 0.002BTC
