Probability Predictions

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 1200 times, we can predict that there will be roughly 1/2 x 1200 = 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.
