Mr. Gamble and Mr. Prude went to the Brain Den Casino, which offered the following game:

A customer bets on a number on a die (1 through 6). The dealer rolls a single die. If the customer’s number comes up, he is paid 4 times his bet, if not - customer loses his bet.

Without delay, Mr. G makes his mind to play 5 rounds betting $1 on number “1” each time. Mr. P, believing the game is in favor of the house offers a side bet, whereby if after 5 rolls Mr. G ends up behind he must pay $5 to Mr. P, otherwise Mr. P pays $5 to Mr. G.

After 5 rounds, what is the average payoff to:

1) BrainDen Casino?

2) Mr. Gamble?

3) Mr. Prude?
