Given:
Number of science students in grade 7 = 20
Number of science students in grade 8 = 20
Total number of students in grade 7 = 22
Total number of students in grade 8 = 28
Solution:
Based on relative row frequency,
The probability of picking a student from grade 7 that is a member of the science club:
[tex]\begin{gathered} \text{Probability = }\frac{Number\text{ of required outcomes}}{Number\text{ of possible outcomes}} \\ =\text{ }\frac{20}{22} \\ =\text{ }\frac{10}{11} \end{gathered}[/tex]
The probability of picking a student from grade 8 that is a member of the science club:
[tex]\begin{gathered} \text{Probability = }\frac{Number\text{ of required outcomes}}{Number\text{ of possible outcomes}} \\ =\text{ }\frac{20}{28} \\ =\text{ }\frac{10}{14} \end{gathered}[/tex]
Going from the probability values obtained, the students of grade 7 are more likely to be science students
Answer: Grade 7 (option A)
