1. Use the World Series as an example. A team must win four out of seven games to win the World Series. The teams must play one less than double the amount of wins for a game to go the full series. 2 * 4 - 1 = 7. For someone to win 75 coin tosses, the coin must be tossed 149 times.
   2 * 75 - 1 = 149. Fred's statement should have been 75 out of 149.

   Another way to look at this is that the first number belongs to the sequence of consecutive positive integers, and the second number is the first number's position in the sequence of positive odd numbers. Any odd number can be found by using 2n - 1. Using the World series as an example: 4 is the number of wins, 2(4) - 1 = 8 - 1 = 7, therefore 4 out of 7. In Fred and Barney's case: 75 is the number of wins, 2(75) - 1 = 150 - 1 = 149, therefore 75 out of 149.
