at a hospital, 56 percent of the babies born are not girls. of the baby girls born, 12 percent are premature. what is the probability of a premature baby girl being born at this hospital? round to the nearest percent.\n0 5%\n0 7%\n0 21%\n0 27%
Answer
Explanation:
Step1: Find the proportion of baby girls
If 56% of the babies are not girls, then the proportion of baby girls is $1 - 0.56=0.44$.
Step2: Calculate the proportion of premature baby girls
The proportion of premature baby girls is the proportion of baby girls times the proportion of premature - among - baby girls. So it is $0.44\times0.12 = 0.0528$.
Step3: Convert to percentage and round
$0.0528\times100% = 5.28%$, rounding to the nearest percent gives 5%.
Answer:
5%
