Ok so I've got a maths question, should be relatively simple but I can't get my brain into gear and want to check what others think.

It's to do with roulette so I'm not after the it won't work etc speech as a few of us are doing this for a laugh/challenge with minimal outlay to see who can get largest % increase on bank before going bust.

Anyway, there are 37 numbers on the table (including 0) which return at odds of 36/1. If you put 1% of your total bank on 35 numbers and get a winner you will be 1% up. Now if you were to back 34 numbers and won you would be 2% up.

Which would be the least riskiest option to get to 2%, betting twice with a 2/37 chance of loss or once with a 3/37 chance?

Answers on a postcard.

4 / 74 = 0,06

3 / 37 = 0,09

If my calculations have anything to do with how this stuff works, it would seem that your risk is higher if betting on 34 numbers.

The less numbers you bet on the more risk there is,

Here is my take on it which is a bit different to the replies; I just don't know which is correct.

1% return = 35/37 numbers = 94.6% chance of winning

2% return = 34/37 numbers = 91.9% chance of winning

Now if you do the 1% return bet twice in a row in my mind you are technically risking 4 chances of a loss against 37 numbers = 33/37 = 89.2% chance of winning.

Therefore, my guess would be a single bet to win 2% return caries less risk.
