**If a student is chosen at random, what is the probability that:**
*Round all answers to 3 decimal places as needed.*
**e) The student competed in Bachata or Bolero, but not FoxTrot?>**

To solve the probability that a randomly chosen student competed in **Bachata or Bolero, but not FoxTrot**, we will analyze the Venn diagram carefully.

### Steps:
1. **Bachata or Bolero, but not FoxTrot** means we are looking at the regions that belong to the Bachata and Bolero circles, but exclude the FoxTrot region. From the Venn diagram, these areas are:
    - The Bachata-only section: 297
    - The Bolero-only section: 330
    - The Bachata and Bolero overlap, but excluding FoxTrot: 360

    These numbers are in the regions that belong only to **Bachata** or **Bolero**, or their overlap without **FoxTrot**.

2. **Total students in Bachata or Bolero, but not FoxTrot**:
    \[
    297 + 330 + 360 = 987
    \]

3. **Total students (from the diagram)**:
    - Add up all the numbers from the Venn diagram:
    \[
    297 + 289 + 352 + 360 + 330 + 312 + 272 + 322 = 2534
    \]

4. **Probability**:
   \[
   P(\text{Bachata or Bolero but not FoxTrot}) = \frac{987}{2534} \approx 0.389
   \]

### Final answer:
The probability that a randomly chosen student competed in **Bachata or Bolero, but not FoxTrot** is approximately **0.389**.
