Calculate Outcomes from Combined Events

In this activity, we will calculate the number of outcomes that are possible in a variety of situations.

When we roll an ordinary die there are 6 possible outcomes.

 

 

If this spinner was spun there would be 8 possible outcomes.

 

 

What can we do with this information?

 

Example

How many possible outcomes are there when we flip a coin and roll an ordinary die?

 

 

Answer

Outcomes include heads and 1, heads and 2 ...etc

For each number on the dice 1-6, we can get heads or tails on the coin.

 

The number of outcomes = 2 x 6 = 12

In this activity, we will investigate outcomes from more than one event.
