How many possible outcomes exist when two fair coins are flipped and a three-section spinner is spin?

9 possible outcomes.

1. There are two coins being flipped.

Possibilities:

HH (two heads) HT (heads and tails) TT (two tails)

There are three sides to the spinner

Possibilities:

Side 1 Side 2 Side 3

Since there are 3 possibilities for each, multiply them together

So, 3*3 which equals 9 possibilities
