    2. Suppose 90% of kids who visit a doctor have a fever, and 20% of kids with a fever have sore throats. What's the probability that a kid who goes to the doctor has a fever and a sore throat? The probability is ______.
    3. The percent distribution of live multiple-delivery births (three or more babies) in a particular year for women 15-54 years old is shown is the pie chart. Find each probability.
    Pie Chart Reads
    15-19- 1.3%
    20-24- 6.9%
    25-29- 22.0%
    30-34- 38.3%
    35-39- 24.9%
    40-44- 5.1%
    45-54- 1.6%
