Paying Bail

Medium

Probability

You have been arrested and need to post bail. You have a bag of $100\$100 bills of which one half are real and the other half are fake. You need to pay $500\$500 for bail. Every time you give the jail a fake bill, the funds you have given are given back to you and you need to start again. How many bills will you have to pull out of the bag on average? Assume the probability of drawing each type of bill is constant per trial.
