. The following relative frequency distribution describes the household incomes for families living in a suburban community:

a) For a randomly selected household, what is the probability that its annual income is less than $80,000?
b) If a household is known to have an income of at least $20,000, what is the probability that its annual income is in the $60,000- under $80,000 category?
c) Two households are randomly selected from those whose income is at least $40,000 per year.
d) Given that the two household have incomes of at least $40,000 per year, what is the probability that both of these households are in the $80,000 or more category?
