Lesson

Coins, Dice, and Compound Events

Probability measures how likely an event is to occur. It lies between 0 and 1, where 0 represents impossibility and 1 represents certainty. Probability helps quantify uncertainty in everyday situations such as predicting rainfall, choosing lottery numbers, or guessing the outcome of a dice roll. The concept builds a bridge between intuition and mathematics by giving numerical meaning to the likelihood of events.

Concept

Trial and Event

A trial is an action whose outcome is uncertain. An event is a collection of one or more outcomes of a trial. 💡 Exam Tip: Write the sample space first whenever possible, then count favourable outcomes carefully. Use the complement rule when that makes counting easier. ⚠️ Common Mistake: Students often skip the sample space and miscount total outcomes or favourable outcomes. 📌 Trigger: Favourable ÷ total
