Question 14 • Geometry

At a high school, students can choose between three art electives, four history electives, and five computer electives. Each student can choose two electives. What is the approximate probability that a student chooses a computer elective and an art elective?

Answer
A
0 point 4 2 4 2 4
B
0 point 2 2 7 2 7
C
0 point 2 1 2 1 2
D
0 point 1 1 3 6 4

Explanation

There are 3 + 4 + 5 = 12 electives, so the number of ways to choose any 2 is 12 × 11 ÷ 2 = 66. For one computer elective and one art elective, there are 5 × 3 = 15 possible pairs. The probability is 15 ÷ 66 ≈ 0.227, so the answer is A, approximately 0.227.
