Respuesta :
Answer: a) 0.922 and b) Yes.
Step-by-step explanation:
Since we have given that
Number of baby girls = 215
Number of baby boys = 18
Total number of children = 215 +18 = 233
We need to find the probability of a girl born to a couple.
so, probability becomes,
P(girls) = [tex]\dfrac{215}{233}=0.922[/tex]
Yes, it is effective in increasing the likelihood that a baby will be girl as the number of girls is more than number of boys.
Hence, a) 0.922 and b) Yes.
The probability of the girl being born to a couple is 0.923. Yes, it is effective in increasing the likelihood that the baby will be a girl as the number of girls is more than the number of boys.
What is probability?
Probability means possibility. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
Given
In a test of a gender-selection technique, results consisted of 215 baby girls and 18 baby boys.
Total children = 215 + 18 = 233
The probability of the girl being born to a couple will be
[tex]\rm P = \dfrac{215}{233}\\\\P = 0.923[/tex]
Thus, the probability of the girl being born to a couple is 0.923.
Yes, it is effective in increasing the likelihood that the baby will be a girl as the number of girls is more than the number of boys.
