The only time I'll lose is if only 2 balls landed on white.

Even if i distrubuted the 800 pesos that way, does it mean I'll only have a little less than 50% probability of winning?

Exactly two balls landing on white and NO yellow: You lose.
Probability of that happening is 49/100*48/99*49/98 + 49/100*49/99*48/98 + 49/100*49/99*48/98 = 36%
Probability of that not happening =64% But don't get excited, 'cos some of your non-losing bets only get a little profit.

e&oe

Dude. No single result on the pay table has a positive expectation. Therefore no combination of wagers has a positive expectation. End of.

Enjoy the dealer. Have fun. Don't expect to make money.

hmmmm My numbers don't match Mikes...... reviewing...

Our point of departure seems to be whether two or more balls can land in the same square. If you look at the video carefully it seems impossible, or at least very unlikely, to me.

Ah....
2red and one white or 3 reds pays 1:1..... lets see....
Probability of 3 reds =(49/100)^3
Probability of 2 reds and one white ( not yellow )= 3 x (49/100)^2 x (49/100)
Therefore probability of 'at least 2 reds and no yellow = (49/100)^3 + 3 x (49/100)^2 x (49/100)=0.352947
but it only pays 1:1
So the house edge on that is 1-2x0.352947=29.41%

If I have that right. Don't walk away. Run away screaming.

hmmmm My numbers don't match Mikes...... reviewing...

Ah.... Because only one ball can go in one pocket....
P 3 reds=49/100 x 48/99 x 47/98 = .1139394 not the 0.117 that I gave... But then Mike had seen the game video.

That wasn't the main problem in your original calculation.

0.352497 = 3 x (49/100)^2 x (49/100). You didn't add the (49/100)^3 to it.

Also, Mike's version doesn't seem to match the OP's.
Mike's numbers make it look like a bet on "2 White" wins if it includes one logo, but the OP's says that all white and red bets lose on any yellow.
Also, Mike shows different bets for one red, two reds, and three reds, and implies that if one wins, then the other two lose, while the OP says that the bets are "(two or mroe) red" and "all red", and both win if all three balls land in red.

Agreed and fixed in edit. Note to self: For questions that don't feature the radical sign, Mike is mostly always right. \$;d)

Wouldn't it be about a 6% house edge when betting on one Red or one White if a Yellow causes all Red/White bets to lose?

Tee Hee. Just Kidding Mike. That Radical sign thing was a revelation to most members, certainly to me.
As punishment to me, the universe has just reminded me of the original 2 dice thread.

Yup, any yellow makes red and white loses. Eg. 1 yellow 2 reds or 1 yellow 2 whites or 1 yellow 1 white and 1 red.

Correct, since I placed a 500 peso bet on 2 reds and 100 peso bet on 3 reds, both of my bets win.

And yes, it has to be 2 or all on the same color (without the yellow, ofcourse).

Thanks guys with the computation and all. Now I know that the way I distrubuted the money on the betting table...I'll have a 36% probability of losing.

Thanks. I amended my post with the tables to show the math both ways. I also didn't know that three reds would be a winner for two reds, which I fixed.
