# Probability

Consider a population of 2000 individuals, 800 of whom are woman. Assume that 300 of the woman in this population earn at least \$60,000 per year, and 200 of the men earn at least \$60,000 per year.

1. What is the probability that a randomly selected individual from this population earns less than \$60,000 per year?

2. If a randomly selected individual is observed to earn less than \$60,000 per year, what is the probability that this person is a man?

3. If a randomly selected individual is observed to earn at least \$60,000 per year, what is the probability that this person is a woman?

#### Solution Preview

Consider a population of 2000 individuals, 800 of whom are woman. Assume that 300 of the woman in this population earn at least \$60,000 per year, and 200 of the men earn at least \$60,000 per year.

Let us make a table- this will make things easier to follow:

Data Given

< \$ 60,000 >= \$ 60,000 Total
Men 200
Women 300 800 ...
