calculating a probability\nat 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.\n5%\n7%\n21%\n27%
Answer
Explanation:
Step1: Find the proportion of baby - girls
If 56% of the babies born are not girls, then the proportion of baby - girls is $100%-56% = 44%=0.44$.
Step2: Find the proportion of premature baby - girls
Of the baby - girls born, 12% are premature. So the proportion of premature baby - girls 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:
A. 5%
