Alice and Maria swim one mile each day. Their times are normally distributed, with a mean of 37 minutes and a standard deviation of 1 minute for Alice, and for Maria a mean of 33 minutes and a standard deviation of 2 minutes. Suppose their times are independent of each other, what is the probability that Alice can beat Maria?
