p = 28 + 62 + 33 33 gives the result in decimals. If you want percents, you could multiply the result by 100.
To find the probability that a geometry student is in the 11th grade, we divide the number of 11th-grade geometry students by the total number of geometry students. For example, if there are 33 geometry students in 11th grade out of a total of 145 geometry students, the probability is approximately 0.227 or 22.7%.
