If you draw a tree to show the number of ways to spin a spinner with five regions twice, how many possibilitdies would there be? There would be possibilities.

There are 5 spaces and 2 slots, so there are 5*5 = 25 different outcomes.

Think of a table that has 5 rows and 5 columns. There would be 25 cells in this table. Each cell is a different outcome.

The probability tree would have 5 branches on the upper level. Then for each upper branch, there are 5 lower sub-branches. Add up all the possible paths and you should find 25 total paths (each path representing a different outcome).
