1. John repeatedly tosses a coin with P(H) = p and Sarah repeatedly tosses a coin with P(H) = q. Assume that John's and Sarah's tosses are independent of each other. Suppose we are interested in the number of trials it takes for each of them to get a head. In this setting, what is the probability that John reaches to a head before Sarah. Show all work.
