There are two jars. One contains nine white marbles and one red marble. The other contains 94 white marbles and six red marbles. If you pick out a red marble you win the game, but you have to choose only one jar to try your luck. Where are your chances best? In the jar with six red marbles but only 6% chance of drawing red, or in the jar with one red marble but a 10% chance?
