Show answer & explanation
Correct answer: D
Solution
Probability = number of favorable outcomes divided by total number of outcomes.
Count the red shoes: 5.
Count the green shoes: 4; total shoes = 5 + 4 = 9.
Probability of drawing a red shoe = 5 (red) ÷ 9 (total) = 5/9.
Answer: 5/9 (already in simplest form).
