Answer 1

1. Caramel candy: 8/30 = 4/15 ≈ 0.2667 (26.67%).

2. Fair coin heads: 1/2 = 0.5 (50%).

3. Spinner with 8 equal numbered sections:
- Probability of landing on a specific number = 1/8 = 0.125 (12.5%).
- (If you mean “landing on a number” at all, that probability is 8/8 = 1.)

4. Green marble: 3/12 = 1/4 = 0.25 (25%).

5. Letter from "MATHEMATICS": total 11 letters, vowels = A,E,A,I = 4 → 4/11 ≈ 0.3636 (36.36%).

6. Student who plays soccer: 12/20 = 3/5 = 0.6 (60%).

7. Blue or green marble: (15+15)/50 = 30/50 = 3/5 = 0.6 (60%).
