Tree Diagram

Today we have been learning about how a tree diagram works and how to use it in maths. We use tree diagrams in maths to show all of the possible outcomes in a question. For example if I had 3 shirts, 2 pairs of pants and 3 pairs of shoes, how many possible outcomes will I have to create a outfit to wear? An easy way to find this out is to time 3 x 3 which is 9 x 2 which is 18 so altogether I would have 18 possible outfits to choose from to wear. I think I have learnt more about tree diagrams and have gained more of an understanding.
