We should compute expected value, if the casino comes out positive, you would want the game

So,

P(rolling a 1)

P(rolling a 3)

P(rolling 2 or 4 or 5 or 6)

Expected value=P(rolling a 1)*($ won by rolling a 1)+P(rolling a 3)*($ won by rolling a 3)+P(rolling 2 or 4 or 5 or 6)*($ won by rolling a 2 or 4 or 5 or 6)

This is a negative number. So if you play this game you will lose money over the long run. So a casino would be happy to have this game
