Question

Use the data to make a tree diagram to show the number of possible outcomes.

(1) Sandy has two skirts: 1 tan and 1 navy. She has three blouses: 1 white, 1 blue,
and 1 red. How many different outfits does she have available?
b
white
tan
navy

Answer 1

Sandy has 6 different outfit combinations available.

The tree diagram shows the possible outcomes for Sandy's outfit choices. She has two skirts (tan and navy) and three blouses (white, blue, and red).

Starting from the top, you can see that there are two options for the skirt (tan or navy). From each skirt option, there are three branch options for the blouses (white, blue, or red).

Multiplying the number of options at each branch, we get a total of 2 skirts multiplied by 3 blouses, which equals 6 different outfit combinations available for Sandy.
