The coin is flipped one more time. A tree diagram has been started for you to represent the possible outcomes. Determine the results from another coin flip. What is the probability that the coin lands heads up all three times?

Each flip has a 1/2 chance of landing heads, and the flips are independent. The probability of getting heads on all three flips is 1/2 × 1/2 × 1/2 = 1/8. So the correct choice is 1/8.
