Pick any random number between 0 and 1 non-inclusive. The next number you pick, you will subtract from your first number. This goes on alternating back and forth between adding to the total and subtracting from the total. What is the expected value of numbers you must pick before the total is greater than 1. Is it infinity? Is it convergent? Not sure where to start. Thanks!
