What selection of snacks shall I pack for the day?

girl and question marks

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

Example

clothes hanger

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
