Finding probabilities for normal distributions in exercise 10, find the indicated probabilities. If convenient, use technology to find the probabilities.

MCAT Scores, In a recent years, the MCAT total scores were normally distribution, with a mean of 500 and a standard deviation of 10.6. Find the probability that a randomly selected medical student who took the MCAT has a total score that is (a) less than 489, (b) between 495 and 507, and (c) more than 522. Identify any unusual events in parts (a)-(c). Explain the reasoning. (Source: Association of American Medical Colleges)
