In a one-tailed probability, we only look at one direction of the distribution. Based on the given problem, we are interested in finding the probability of getting a score higher than 72.5. This means we only look at the upper tail of the distribution. The area under this upper tail is 0.045, which is the same as the answer provided. Therefore, the best choice for a one-tailed probability is A.
