balance 6234 mb (1/2 = 3117mB)

wagered = 98456mB = lvl 6 = 0.9% house edge

first roll: 3117mB on 49%; loss total wagered: 101573mb = lvl 7 =0.88% house edge = -3117mB profit

second roll : 3117 mB on 49% , @ 0.88 house edge win

= +3188.2 mB profit

total session profit = -3117mB + 3188.24571mB

=+71.24571mB

sorry if process is a bit blurry, had to do it fast, haha! hope its correct though..

USERNAME: CASIO

Yes, you got it correct. Cheesy

Trivia Winner : CASIO

10 mBTC sent.

Runner-ups: (1 mBTC each)
forfuna, kshyzer and fumblingperch. Your answers are correct. Good job and Keep it up.

kshyzer has however taken a different interpretation of the problem which is not wrong though I hadn't thought of taking it that way. The decimal and the thousands separator is taken to be of the same as Rollin uses.

Question : X, who has wagered 98,456 mBTC has a balance of 6,234 mBTC at Rollin at the time. He bets half of the balance at 49% win chance and loses and then goes all-in at 49% win chance and wins. What is his profit or loss? Show working.

Level House Edge Wagered amount
6 0.90 % 50000 m฿
7 0.88 % 100000 m฿

Let us check the first bet,
Bet : 3117 mBTC
Win chance : 49%
House Edge : 0.9%
Result : Lose
Payout : 0.

New Level 7. (Since the total wagered now passes 100,000 mBTC)

And the second bet,
Bet : 3117 mBTC
Win chance : 49%
House Edge : 0.88%
Result Win
Payout : 6305.24571 mBTC

Total bet : 6,234 mBTC
Total payout : 6305.24571 mBTC

Profit: 71.24571 mBTC

On-thread Trivia!

aaaand the question for today is:

Q. X, who has wagered 98,456 mBTC has a balance of 6,234 mBTC at Rollin at the time. He bets half of the balance at 49% win chance and loses and then goes all-in at 49% win chance and wins. What is his profit or loss? Show working.

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 of 10 mBTC.

Remember, no edits.

Total Wager is 98456 mbtc
Level 6 - House Edge is 0.90%

Playing half of 6234mbtc and lost, so he have 3117mbtc now

Total Wager is 101573mbtc, now he is level 7 with house edge on 0.88%

Now he plays 3117mbtc 49% win chance with 0.88% house edge = 3117mbtc * (100 - 0.88) / 49 = 6305.24571mbtc

his profit is 6305.24571mbtc - 6234mbtc = 71.24571 mbtc

Q. X, who has wagered 98,456 mBTC has a balance of 6,234 mBTC at Rollin at the time . He bets half of the balance at 49% win chance and loses (Step1) and then goes all-in at 49% win chance and wins (Step2). What is his profit or loss? Show working. (Step 3)

1   1.00 %   0.00500 m฿   0 m฿ <<<---
2   0.98 %   0.01000 m฿   500 m฿
3   0.96 %   0.01500 m฿   1000 m฿

Wager = 98,456 mBTC = Level 1

Initial Balance = 6,234m฿

---> Step 1 (Playing 49% win with half of initial balance)
Half of Balance = 3,117m฿
Playing at 49% win with 3,117m฿ (lost it)
Balance = 3,117m฿

---> Step 2 (Playing all-in at 49% win with remain balance)
Remain Balance = 3,117m฿
Playing at 49% win with 3,117m฿ = +3.18061m฿ profit (win)
Balance = 3,117m฿ + 3.18061m฿ = 6,29761m฿

---> Step 3 (his final profit or loss)
Initial Balance = 6,234m฿
Balance = 6,29761m฿
Final Balance = 6,29761m฿ - 6,234m฿ = 0,06361m฿

Loyce here, I agree Cheesy

Although you could argue the house edge 0.9% is totally irrelevant for the first roll. House edge only matters if you win.
Bonus Solution: X could get an extra 12 mBTC profit by entering the Bet for it Contest Code S1, either one of the bets would qualify. That would bring the total profit to 83.24571 mBTC Wink

at first , he wagged 98456mB <=> lv6 <=> 0.9 HE
he bet half (3117) and lost , till now the profit is -3117
he got lv up ( lv 7 = 100000mB+ , he got 101573 after he bet ) <=> 0.88 HE
he bet again and won

so it's gonna be (3117*(100-0.88)/49-1) = 3188.24571

=> total sesion profit : 3188.24571 + (-3117) = 71.24571

this is my most detailed solution for your questions Cheesy

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 of 10 mBTC.

Remember, no edits.

he has zero profit zero loss

since he has 98456 mBTC wagered so it mean he now at lvl 6 and has 0.9% HE
the first roll is half of the balance 6234 mBTC x 50 % = 3117 mBTC and lose
the second roll the remaining balance 3117 mBTC x (100-0,9)/49 = 6303,97347

so total profit the last balance - initial balance = 6303.9734 mBTC - 6234 mBTC = 69,97347 mBTC

so at the end his profit is 69,97347 mBTC
