What is the expectation of this game?
I've been playing a game on jackpotjoy.com all day called "Lucky Dice." In the game you throw three dice, and I bet 10 points on one, 10 points on two and 10 points on three.
So if none of the die come up one/two/three I lose the 30 points I bet. if any one die comes up one/two/three I get 20 points back (so I lose 10 overall) if any two die are the same and come up with one/two/three I get 30 points (so I lose nothing overall) if all three are the same and come up with one/two/three I get 100 points (so I get 80 points overall) so for example if the die roll as ... one, one, five. I get thirty points but I bet thirty points so overall I get nothing. if they rolled as four, five six I get nothing (so my net gain is -30) if they rolled as one, two, three I get 20 back for each (net gain is 30) if they rolled as one, one, three I get 50 back, (so my net gain is 20) ANyway, enough examples. The reason I'm going on about it is it seems to have really good return, like a really high positive expectation. And given that I've been playing all day I really am quite surprised to be still winning. Does soembody familiar with basic probability want to calculate expectation for my strategy? |
