1. Even numbers: 2,4,6,8 (4 out of 8). Probability = 4/8 = 1/2 = 50%.

2. Green marbles: 3 out of 12. Probability = 3/12 = 1/4 = 25%.

3. "MATHEMATICS" has 11 letters; vowels A, E, A, I = 4. Probability = 4/11 ≈ 36.36%.

4. 12 of 20 students play soccer. Probability = 12/20 = 3/5 = 60%.

5. Blue or green: (15+15)/50 = 30/50 = 3/5 = 60%.
