The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). The mean maximum oxygen uptake for elite athletes has been found to be 80 with a standard deviation of 8.1. Assume that the distribution is approximately normal.

a) What is the probability that an elite athlete has a maximum oxygen uptake of at least 75 ml/kg?

b) What is the probability that an elite athlete has a maximum oxygen uptake of 50 ml/kg or lower?
