1. **State the problem:** We have 980 married women surveyed about having a career and/or a child.
Given data:
- Total women surveyed: 980
- Checked "Child" box: 320
- Checked "Career" box: 72
- Checked neither box (blank): 603
2. **Define sets:**
Let $C$ = set of women with a career.
Let $H$ = set of women with a child.
3. **Use the formula for union of two sets:**
$$|C \cup H| = |C| + |H| - |C \cap H|$$
4. **Calculate the number of women who checked at least one box:**
$$|C \cup H| = 980 - 603 = 377$$
5. **Substitute known values to find the intersection:**
$$377 = 72 + 320 - |C \cap H|$$
$$|C \cap H| = 72 + 320 - 377 = 15$$
6. **Find the number of women who checked only career or only child:**
- Only career: $$|C| - |C \cap H| = 72 - 15 = 57$$
- Only child: $$|H| - |C \cap H| = 320 - 15 = 305$$
7. **Summary for Venn diagram:**
- Career only: 57
- Child only: 305
- Both career and child: 15
- Neither: 603
This completes the Venn diagram values.
