![### Probability Question: Knowledgeable Football Fans
**Problem Statement:**
Sixty-five percent of men consider themselves knowledgeable football fans. If 12 men are randomly selected, find the probability that exactly five of them will consider themselves knowledgeable fans.
**Multiple Choice Options:**
- A. 0.059
- B. 0.204
- C. 0.417
- D. 0.650
This question can be approached using the binomial probability formula, which is used to compute the probability of exactly \( k \) successes (in this case, five men considering themselves knowledgeable football fans) out of \( n \) trials (in this case, 12 randomly selected men), given the probability \( p \) of success on a single trial.
#### Explanation of the Binomial Probability Formula:
\[ P(X = k) = \binom{n}{k} \cdot p^k \cdot (1-p)^{n-k} \]
Where:
- \( n \) = 12 (number of trials)
- \( k \) = 5 (number of successes)
- \( p \) = 0.65 (probability of success)
- \( \binom{n}{k} \) is the binomial coefficient, calculated as \( \frac{n!}{k!(n-k)!} \)
##### Steps to Calculate:
1. **Calculate the Binomial Coefficient**:
\[ \binom{12}{5} = \frac{12!}{5!(12-5)!} \]
2. **Calculate the Probability**:
\[ P(X = 5) = \binom{12}{5} \cdot (0.65)^5 \cdot (0.35)^7 \]
Using these steps and probability calculations, one arrives at the final answer, which corresponds to one of the multiple-choice options provided.
This problem serves as an excellent exercise in understanding how to apply binomial probability in practical scenarios and interpret statistical data accurately.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8d7dd878-68eb-4c6b-9d67-0903dd8963d8%2F200de128-0619-4cfd-97fa-a2cca5c277ab%2F02hau2c_processed.jpeg&w=3840&q=75)
