In a football match, Ronaldo makes 4 goals from 10 penalty kicks. The probability of converting a penalty kick into a goal by Ronaldo, is
(a)`1/4`
(b) `1/6`
(c) `1/3`
(d) `2/5`

Options

A. `1/4`
B. `1/6`
C. `1/3`
D. `2/5`

Answer

To find the probability of Ronaldo converting a penalty kick into a goal, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the total number of penalty kicks**:
Ronaldo took a total of 10 penalty kicks.

2. **Identify the number of successful goals**:
Out of those 10 penalty kicks, Ronaldo scored 4 goals.

3. **Determine the number of favorable outcomes**:
The number of favorable outcomes (successful goals) is 4.

4. **Determine the total number of outcomes**:
The total number of outcomes (total penalty kicks) is 10.

5. **Use the probability formula**:
The probability \( P \) of an event is given by the formula:
\[ P(\text{event}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \]

6. **Substitute the values into the formula**:
\[ P(\text{goal}) = \frac{4}{10} \]

7. **Simplify the fraction**:
\[ P(\text{goal}) = \frac{4 \div 2}{10 \div 2} = \frac{2}{5} \]

8. **Conclusion**:
Therefore, the probability of Ronaldo converting a penalty kick into a goal is \( \frac{2}{5} \).

### Final Answer:
The probability of converting a penalty kick into a goal by Ronaldo is \( \frac{2}{5} \).
