An unbiased coin is flipped three times. Draw a flow chart of the possible outcomes.

1. Quantify the sample space: How many possible outcomes are there?
2. Quantify an event: How many ways can the coin land on heads on every toss? Find the probability: What is the probability of the coin landing on heads on every toss?
3. Quantify an event: How many ways can the coin land on heads at least once? Find the probability: What is the probability of the coin landing on heads at least once?
4. Quantify an event: How many ways can the coin land on tails at least once? Find the probability: What is the probability of the coin landing on tails at least once?
5. Quantify an event: How many ways can the coin land on heads exactly two times? Find the probability: What is the probability of the landing on heads exactly two times?
