Guest Posted May 4, 2009 Report Share Posted May 4, 2009 You have 10 red balls and 10 yellow balls. You need to place the balls in 2 bags. The judge said if he pulls a red ball you get life in jail and if he pulls a yellow one then you are free to go. Which balls do you put in each bag so that you have a 73% chance of going free.

0 Guest Posted May 4, 2009 Report Share Posted May 4, 2009 Place all 10 red balls and 9 yellow balls in one bag, and 1 yellow ball in the other. You'd have a 100% chance of going free with bag #2. And a 9/19 or 47.3% chance in bag #1. Averaged out, you'd have a 73% chance of going free. Quote Link to comment Share on other sites More sharing options...
