Respuesta :
If the likelihood of boys being born is 56%, then the complement of that is the likelihood of girls being born which is 100% - 56% = 44%.
Since we are given that of the baby girls born, 12% are premature, the probability of a premature baby girl being born is:
(0.44)(0.12) = 0.0528 or 5.28%
The closest answer is the FIRST OPTION (5%).
Since we are given that of the baby girls born, 12% are premature, the probability of a premature baby girl being born is:
(0.44)(0.12) = 0.0528 or 5.28%
The closest answer is the FIRST OPTION (5%).
The percentage that represents the probability is 5%, so the correct option is the first one.
How to find the probability?
We know that 56% of the babies are boys, then the other 44% are girls.
We also know that 12% of the babies are premature, then the percentage of babies that are girl and premature is given by the product between the two percentages in decimal form:
0.12*0.44 = 0.0528
To get it in percentage form, we get:
100%*0.0528 = 5%
So the correct option is the first one.
