Pierre and Blaise are discussing the probability of flipping two coins and having one come up heads and one come up tails. Pierre
states the sample space for a two-coin flip is (HH, TH, HT, 77). Blaise argues that (TH) and (HT) are the same outcome, so the
sample space is really just (HH, TH, 77). What is the probability of one heads and one tails using each sample space, and who is
correct? How could someone test this experimentally??
