It looks like you're working on a probability problem related to opinions on increasing fees within a group that includes students, administration, and faculty members. Let's address each part you've mentioned to ensure clarity and accuracy. --- ### **b. Probability of Being Both a Student and Against Increasing the Fees** **Question:** *What is the probability that a person selected at random is both a student and against increasing the fees?* **Solution:** To determine this probability, you'd typically use the formula for the intersection of two events: \[ P(\text{Student and Against}) = P(\text{Student}) \times P(\text{Against} \mid \text{Student}) \] However, without specific data (e.g., the total number of individuals, the number of students, and how many students are against increasing fees), we can't compute a numerical answer. If you provide the relevant data, I'd be happy to help calculate it! --- ### **c. Probability of Being Either Administration or Against Increasing the Fees** **Given Answer:** \[ \frac{399}{2504} \] **Verification:** Assuming there's no overlap between administration members who are against increasing fees and others: \[ P(\text{Administration or Against}) = P(\text{Administration}) + P(\text{Against}) - P(\text{Administration and Against}) \] If \( P(\text{Administration and Against}) = 0 \) (i.e., no administration member is against the fees), then: \[ P(\text{Administration or Against}) = P(\text{Administration}) + P(\text{Against}) = \frac{399}{2504} \] Your provided answer seems correct based on this assumption. --- ### **d. Probability of Being Both in Favor of and Against Increasing the Fees** **Question:** *What is the probability that a person selected at random is in favor of increasing the fees and is against increasing the fees?* **Given Options:** - 0 - 0.2504 **Solution:** Being **in favor** and **against** increasing the fees are **mutually exclusive** events. This means a person cannot simultaneously hold both opinions. \[ P(\text{In Favor and Against}) = 0 \] **Conclusion:** The correct probability is **0**. --- ### **e. Probability that a Faculty Member is Against Increasing the Fees** **Given Answer:** 0.279 **Verification:** Assuming you've calculated this based on the relevant data (e.g., number of faculty members against the fees divided by the total number of faculty members), the answer seems plausible. Ensure that the calculation considers only faculty members and not the entire population. --- ### **Summary** - **Part d:** The probability that a person is both in favor of and against increasing the fees is **0**, since these are mutually exclusive events. If you have specific data or further questions about other parts, feel free to share them, and I can assist you more comprehensively!
