In this worksheet, students will use probability to predict how often an event is likely to happen. Key stage:  KS 3

Difficulty level:   #### Worksheet Overview

Probability is written as a fraction and can be used to predict the number of times an event will happen when an experiment is carried out a large number of times.

Example The probability of throwing tails on a coin is 1/2.

If we throw the coin 1,200 times, we can predict that there will be roughly 1/2 x 1,200 = 600 tails.

Example The probability of throwing a 4 or 5 on a die is 1/3.

In 600 throws, we can predict that there will be roughly 1/3 x 600 = 200 fours or fives thrown.

Let's have a go at some questions.
