Example: Student Subject Preferences
A school surveys 100 students about their favorite subject:
| Math | Science | English | Total | |
|---|---|---|---|---|
| Year 10 | 15 | 20 | 10 | 45 |
| Year 11 | 25 | 15 | 15 | 55 |
| Total | 40 | 35 | 25 | 100 |
Probability Calculations:
- P(Year 10 student) = 45/100 = 0.45
- P(prefers Math) = 40/100 = 0.4
- P(Year 10 and Math) = 15/100 = 0.15
- P(prefers Math | Year 11) = 25/55 = 5/11

Practice Questions for Two-Way Tables
A two-way table shows information about 80 students. It shows whether they study French or Spanish, and whether they are in Year 10 or Year 11. The total number of Year 10 students who study French is the value found by looking at which intersection?
