## Ratio of Boys and Girls Solution

Assume there is N number of couples, so there would be N boys. The number of girls can be calculated by the following method.

Number of girls = 0*(Probability of 0 girls) + 1*(Probability of 1 girl) + 2*(Probability of 2 girls) + â€¦

Number of girls = 0*(N*1/2) + 1*(N*1/2*1/2) + 2*(N*1/2*1/2*1/2) + â€¦

Number of girls = 0 + N/4 + 2*N/8 + 3*N/16 + â€¦

Number of girls = N

Using mathematical formulas, it becomes apparent if you sum up the first 4-5 terms.

The proportion of boys to girls is 1:1.

**As such, the answer would be 1.00.**
