After failing to convince Brandon to put number theory problems in his Jeopardy, Ian decides that in his senior year he will make 128 number theory-themed Jeopardies everyday until the end of time. Unfortunately, Ian loses motivation and on the second day makes 64 jeopardies and 32 on the next day. On the 31st day, Ian only makes 0.000000009% of a Jeopardy. After an infinite amount of time, how many has he made?

Julia has recently won 2 billion dollars by selling her company SmartPaperClips and Co. To choose the percent of money (between 0-1 and 0-100%) she would like to put into her savings account a fair coin is flipped. If it lands heads, then it is flipped again and the chosen number is 0 if the second flip is heads, and 1 if the second flip is tails. On the other hand, if the first coin flip is tails, then the number is chosen uniformly at random from the closed interval [0,1]. Two random numbers x and y are chosen independently in this manner. What is the probability that |x-y|>1/2?
