In a certain city, 60% of the heads of household own the house in which they reside, and 80% of the heads of the
household have full-time employment. When considering what percentage of heads of household both own their
home and have a full-time job, a student estimates that 48% of heads of household fit both requirements, stating
that (0.60)(0.80) = 0.48. Is this student correct in his approach?
O Yes, these two events are most likely independent, so the joint probability can be found by multiplying the
individual probabilities
O No, because although two probabilities should be multiplied, it should not be these two probabilities. This is
because the two events are likely not independent,
O No, these two events are most likely not independent, so the joint probability cannot be found by multiplying the
individual probabilities. They should be added instead.
O Yes, the joint probability can always be found by multiplying the individual probabilities
