The total number of 7th-grade students who do not read on grade level is 43%+28% = 0.71*200 = 142
If a Springfield middle school student is selected at random, there is a 0.28 probability that he or she reads on grade level.
Probability = Favorable options/Total options
Total options = 600
Favorable options = 0.24*200+0.29*200+0.32*200 = 48+58+64 = 170
Probability = 170/600 = 0.28
