Consider two coins, one fair and one unfair. The probability of
getting heads on a given flip of the unfair coin is 0.10. You are
given one of these coins and will gather information about your
coin by flipping it. Based on your flip results, you will infer
which of the coins you were given. At the end of the question,
which coin you were given will be revealed.
When you flip your coin, your result is based on a...

Slim and Roy are flipping a unfair coin, where the coin has the
chance to land on heads 65% of the time. Every time that the coin
lands on heads, Slim gets 500 dollars from Roy, and Roy gets 500
dollars from Slim if the coin lands on tails. If the game is played
100 times (coin is flipped 100 times), what is the probability that
Slim's winnings are $20,000 more than Roy's, where 'x' is strictly
greater than 20,000...
