Question 18 • Geometry
There are 10 marbles total, so the number of ways to draw 2 is 10 × 9 ÷ 2 = 45. To get one orange and one green, there are 2 choices for the orange and 2 choices for the green, giving 2 × 2 = 4 favorable pairs. The probability is 4 ÷ 45 ≈ 0.0889, so the approximate probability is 0.08889, choice C.
