From weather forecasts to sports betting, probability helps us make sense of uncertain events and make informed decisions.

Exam Tips
- Always simplify fractions - write 1/2 instead of 3/6
- Check your answer makes sense - probability cannot be negative or greater than 1
- Read the question carefully - "at least one" is different from "exactly one"
- Use clear notation - write P(A) for "probability of event A"
- Show your working - write the fraction before converting to decimal
- Be careful with units - some questions want decimals, others want percentages or fractions
