Flipping a coin question?

You are out with friends. Half of you want to go bowling and the other half want to go to a movie. How will you make a fair decision about whether to go to a movie or go bowling using a fair coin and assuming that all of you want to go to either of the places together? (Let H = heads and T = tails)

1 Flip the coin twice. If the outcome is in the sequence HH, go to the movie. If it is not HH, go bowling.

2 Flip the coin twice. If the outcome is in the sequence HT, go to the movie. If it is TH, go bowling or repeat the process. @iGreen

3    Flip the coin three times. If the outcome is in the sequence HHT, go to the movie. If it is TTT or HHH, go bowling; otherwise, repeat the process.
