To find the probability that a randomly selected student is under 37 years old, add the number of students in all age groups under 37 years old and divide by the total number of students. This includes the groups under 21, 21-24, 25-28, 29-32, and 33-36, which sum to 412 + 416 + 274 + 157 + 103 = 1362. The total number of students is 1511. Thus, the probability is 1362 / 1511 = 0.901 (rounded to three decimal places).
