To determine the percentage of chances that the basketball player scored, follow these steps:
1. Identify the total number of attempts and successful scores:
- Total attempts: 20
- Successful scores: 8
2. Set up the formula to find the percentage of successful scores:
- The formula to calculate the percentage is: [tex]\[(\text{Successful Scores} / \text{Total Attempts}) \times 100\][/tex]
3. Substitute the given values into the formula:
- Successful Scores = 8
- Total Attempts = 20
- [tex]\[(8 / 20) \times 100\][/tex]
4. Compute the percentage:
- First, perform the division: [tex]\[8 / 20 = 0.4\][/tex]
- Then, multiply by 100: [tex]\[0.4 \times 100 = 40\][/tex]
Thus, the basketball player scored 40% of his chances. Therefore, the correct answer is:
40%
