Response:

Choice B

Detailed breakdown:

With 200 students in total in the 7th grade

The percentage of volleyball players is 12% = 24

The percentage of baseball players is 15% = 30

Those who play both sports are 4

We need to determine the probability of a student being involved in either volleyball or baseball

The count of students who play either sport is

24+30-4= 50

The probability for a student playing either volleyball or baseball

= $\frac{50}{200} =0.25$

Expressed as a percentage, this equals 25%

So, option b

P(volleyball and baseball) = 4/200 x 100 = 2%
P(volleyball or baseball) = P(volleyball ∪ baseball) = P(volleyball) + P(baseball) - P(volleyball and baseball) = 12% + 15% - 2% = 25%.

Thus, 25% of students participate in either volleyball or baseball.
