Probability: Chance, Outcomes and Events
A short read for Class 8 before you play. These notes cover Probability.
🪙 Outcomes and events
An experiment such as tossing a coin or rolling a die has possible outcomes, and an event is the set of outcomes we want. A coin has 2 outcomes, a die has 6, and two coins have 4. Equally likely outcomes have the same chance.
🎯 Probability
Probability is the number of favourable outcomes divided by the total number of outcomes. On a die, an even number has 3 favourable outcomes out of 6, so the probability is 1/2. Probability always lies between 0 and 1.
📏 Sure and impossible events
A sure event always happens and has probability 1, while an impossible event never happens and has probability 0. The chance of an event and the chance of it not happening add up to 1, or 100 percent.

Key ideas and facts to know
| Event | Favourable | Probability |
|---|---|---|
| Head on a coin | 1 of 2 | 1/2 |
| Even on a die | 3 of 6 | 1/2 |
| Six on a die | 1 of 6 | 1/6 |

Solved examples
Total = 12, so blue = 12 - 4 = 8.
There are 11 letters and M appears twice, so P = 2/11.
Common mistakes
| Mistake | Correct idea |
|---|---|
| Giving a probability above 1 | It can never exceed 1 |
| Counting outcomes twice | List each outcome once |
| Thinking 10 tosses must give 5 heads | Probability is chance, not certainty |
Probability in daily life
Probability appears in weather forecasts, games, sports, lotteries, quality checks and any decision made under uncertainty.
Tips for parents and teachers
- List all outcomes first.
- Check the answer lies between 0 and 1.
- Practise one assertion and one case study each week.
