christy asked:


If you bet $100 on a single number in Roulette, what is your expected gain? ( There are 38 spaces on the wheel, and winning number earns a payoff of $35 for every dollar bet.)

How do you set this problem up and solve it>>??

Thank you

The house advantage is 5.26%.

Vegas Matt- is incorrect. Not all bets pay the same. A top-line bet pays less (5 numbers 0,00,1,2,3). It pays 6 to 1, so you lose an extra unit when factored out. The house edge is @7.75% - the worst bet in roulette!

Here’s how you do the math:

Say you bet $1 on the number one, 38 spins in a row. The magic roulette wheel you play on hit every number once, consecutively (i.e., it hit 1, then 2, then 3, etc). So, on the first spin, you won $35 (plus has your $1 returned), then lost all the other spins.

So, after 38 spins, you’ve lost $37, and won $35, for a net lose of $2. Divide that $2 by 38, and you’ll find that you lose $.0526 per spin. Expressed as a percent (how ‘house edge’ is usually written), that’s 5.26%.

You can follow this same procedure for any bet on the table, and you will get the same result.

I’ve spent years devising a unique roulette system that actually works.

My Roulette System
Probability Statistics

47.37 % Of Getting Your Money Back
31.59 % Of Making A 50 % Profit
21.04 % Of Losing Total Bet

I like those odds.

bpcustom: You think your clever dont you? all of those percentages add up to 100% not 94 with a 5% house advantage. you dont know what your talking about, youre just jealouse.
and fyi, ive tested this method dozens of times, and i have never gone broke

with a smart a$$ response like what u gave me you deserve to be bashed over the head with something hard

Princess has apparently spent years devising a system that tells us what we already know about Roulette.

(.4737 * 1) + (.3159 * 1.5) + (.2104 * 0) = .9476

Which is a house advantage of 5.25%

Have fun going broke.

The payout for a single number is 35:1

there are either 37 or 38 spaces on roullette wheels, in america, most often it is 38 so we will say the odds are 1:38

the house advantage lies in those extra spaces, so the edge is 1 or 2 divided by 38

The house edge on Roulette is 5.26% on a fair American wheel.

So on average you are going to lose $5.26 each time you bet $100.

Of course that is the long term average. In 10 spins you could hit the right number every single time, or not at all and lose a grand.

Jo s is right but so is Vegas Matt it just seems that he forgot a bet.
