According to the National Vital Statistics Report, 20.1% of all
pregnancies result in weight gain in excess of 40 pounds (for
singleton births). In addition, 49.5% of all pregnancies result in
the birth of a baby girl. Assuming gender and weight gain are
independent, what is the probability randomly selected pregnancy
results in a girl and weight gain in excess of 40 pounds?
ANSWER: Write your probabilities
with a leading zero and round to 2 decimal places. Example:
0.008 would round to 0.01
P(baby girl & more than 40 lb weight gain) =
