The formula for a probability is given by the next from:
[tex]P=\frac{\#\text{ number of favorable outcomes}}{Total\text{\# of posible outcomes}}[/tex]We need to find the probability that by randomly selecting a child, the result will be a female.
The sample is:
1,791,408 males
1,785,070 females
Hence, there are 1,791,408 +1,785,070 = 3,576,478 total children.
Replacing on the formula:
[tex]P=\frac{1,785,070}{3,576,478}=0.499113[/tex]Therefore, the probability is given by 0.499113...
Rounded to the nearest tenth:
P=0.5
