#2 xx 2 = 4# outcomes

There are 4 possible outcomes.

For the dime there are 2 outcomes, Head or Tail

For the quarter there are 2 outcomes, Head or Tail

The 2 outcomes are independent of each other so there are

#2 xx 2 = 4# outcomes

If a third coin were to be flipped there would be:

#2xx2xx2 = 8# outcomes
