Fair Dice Games: win $5 if doubles: price for fair game?

[winniebabie]

David rolls a pair of dice. He will win $5 if he throws doubles. For the game to be fair, how much should the person pay the game?

I came up with 20 bucks? right or so wrong?

Re: FAIR DICE GAMES

well, 1/6 would be for him getting a double and 5/6 would be against him rolling a double.
so 1*5=5
and 5*5-25
25-5=20

dont know what i am doing? no judgment my way please, lol

Just think for a minute, Winnie:
would you pay $20 to get a chance to win $5 ?
