TRY THIS AT HOME !!

Mr. Rankin is trying to figure out all the possible combinations for the grade 5/6 co-ed 4x100 metre relay team. He has Salina, Kennedy, Zach and Andrew to choose from. He needs our help!! Can you figure out how many possible combinations there are for the relay? Make sure to show all your work. Hint: if you're stumped look at the video I posted a few days ago on how to make a tree diagram.
