If you flip a coin 3 times how many possible outcomes are there?

There are 2 possibilities for each toss. Since the three tosses are independent (one trial does not affect the outcome of the other trials), there are 2 * 2 * 2 = 8 total possible outcomes.

The outcomes are:

HHH

HHT

HTH

HTT

THH

THT

TTH

TTT
