Question

In a given year, 1,791,408 males and 1,785,070 females were born in a certain country. If a child is selected randomly from this group, what is the probability that it is female?The probability is?

Answer 1

The formula for a probability is given by the next from:

`P=\frac{\#\text{ number of favorable outcomes}}{Total\text{\# of posible outcomes}}`

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:

`P=(1,785,070)/(3,576,478)=0.499113`

Therefore, the probability is given by 0.499113...

Rounded to the nearest tenth:

P=0.5
