Amelia has a coin that lands heads with probability 31, and Blaine has a coin that lands on heads with probability 52. Amelia and Blaine alternately toss their coins until someone gets a head; the first one to get a head wins. All coin tosses are independent. Amelia goes first. The probability that Amelia wins is qp, where p and q are relatively prime positive integers.
