3. Describe the sample space for the indicated experiment.
A coin is tossed four times.
Let H denote Heads and T denote Tails.
For each toss, there are two possible outcomes = H or T
The required sample space is:
S = {HHHH, HHHT, HHTH, HTHH, THHH, HHTT, HTHT, HTTH, THHT, THTH, TTHH, HTTT, THTT, TTHT, TTTH, TTTT}
