Assuming 22% of infants delivered in a small-town record
low-weight. Among these infants, 30% belongs to households that are
considered poor. Looking at it all, only 25% of infants not
recorded as low-weight are delivered to poor households.
- What percent of all infants delivered in this small-town were
delivered to households that are poor or poor households?
- What is the probability that an infant delivered to a poor
household would be noted as low-weight?
- If a group is randomly selected of 4 infants recorded as
low-weight and 6 infants recorded as not low-weight. Considering
this randomly selected group of 10, compute the probability that
you can have exactly 2 infants delivered to poor households?
