Suppose that there is a 10% probability that any given person in a population is left-handed, and
a 90% probability they are not left-handed.
Say we randomly select 2 people and categorize them as left-handed (L) or not (N). Here is a
sample space showing the possible outcomes:
1st person 2nd
N

Let X represent the number of left-handed people in the pair.
