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
