Suppose that 3 people toss an unfair coin that has a probability 1/4 of landing on a head, and 3/4 on a tail. The person who is the odd one out (their coin lands on a different side) pays for lunch. If all coins turn up the same, they are tossed again. Find the probability that fewer than 4 tosses are needed to find the person who pays for lunch.
