**Combinations** appear regularly in everyday life.

For example, what could I have on my toast for breakfast?

What selection of snacks shall I pack for the day?

What should I wear today?

To work out the total number of combinations, we can multiply together the numbers of the different options.

__Example__

At Jack's school there are some uniform choices:

short sleeve T-shirt, short sleeve shirt, long sleeve shirt

grey trousers, grey shorts

jumper, blazer

How many different combinations are there?

__Answer__

There are **3** top options

There are **2** bottom options

There are **2** jumper options

So there are **3 x 2 x 2 = 12 **possible combinations

Let's have a go at some questions.
