=========
Note: that listing is called the "sample space" for the experiment
of tossing 4 coins as it lists all the possible results.
=========
Now count the number of coutcomes that have "exactly 3 heads".
=========
The probability of exactly 3 heads is the number of outcomes that
have 3 heads divided by the total number of possible outcomes.
