There are 200 students in the 7th grade class at manchester middle school. of these students, 22% play football and 12% play baseball. eight students play on both teams. what is the probability that a student plays either football or baseball? a. 38% b. 34% c. 26% d. 30%

The percentage of the students playing football and baseball is equal to,
                                    (8 / 200) x 100% = 4%
The probability of the students playing either football or baseball is,
                P(f or b) = P(f) + P(b) - P(f and b)
Substituting from the known values,
                P(f or b) = 0.22 + 0.12 - 0.04 = 0.3
Thus, the final answer is 30% which is letter D.
