10-62.

^{®} player has four tiles with the letters A, N, P, and S.

How many arrangements of these letters are possible?

Draw a tree diagram that shows how to get the arrangements and explain how a decision chart represents the tree.

There are four decisions to make, but not every decision has the same number of available choices to pick from.

What is the probability of a two-year-old randomly making a word using the four letters?

Those tiles can be used to spell PANS, NAPS, SNAP and SPAN.
