In a recent year, the MCAT scores for the critical analysis and reasoning skills portion of the test were normally distributed, with a mean of 124.9 and a standard deviation of 3.0. Find the probability that a randomly selected medical student who took the MCAT has a critical analysis and reasoning skills score that is 

(a) Less than 120, 

(b) Between 122 and 128, and 

(c) More than 130. Identify any unusual events in parts (a)–(c). Explain your reasoning.

Find the indicated probabilities. If convenient, use technology to find the probabilities.
