294. You have 50 coins totaling $1.00. You drop one down an open drain while
tossing the coins in your hand. What is the chance that you have lost a quarter?

There are 2 ways you can have fifty coins totaling $1.00. 2 dimes, 40 pennies, and 8 nickels; or 2 dimes, 45 pennies, two nickels, and 1 quarter. These arrangements are equally probable, so there is a one-half chance you had a quarter to begin with. The probability that you then dropped that quarter from all the coins in you hand is one fiftieth. Therefore, the total probability that you lost a quarter is one half times one fiftieth, or one one-hundredth.
