How do you guys figure the odds are not cumulative?

Consider flipping a coin with an even chance of coming up heads (H) or tails (T).
With one flip, the two possible outcomes are H or T, so heads has a 1:2 (50%) chance.
Flip the coin twice and the possible outcomes are HH, HT, TH, or TT, so now there is 3:4 (75%) chance of having heads come up at least once.
Flip the coin 3 times and the outcomes are HHH, HHT, HTH, HTT, THH, THT, TTH, or TTT, so there is now a 7:8 (87.5%) chance of having heads come up at least once.
The more times you flip the coin, the higher the likelihood you will get at least one heads. No matter how many times you flip the coin, however, will the chance ever reach 100%.
