Kierra Mcconnell · Answer 1

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.
