hi i have one of the answer to your question

The question:
“in a country in which people only want boys, every family continues to have children until they have a boy. if they have a girl, they have another child. if they have a boy, they stop. what is the proportion of boys to girls in the country?
”

MATHEMATICALLY:

The answer:
” about 1:1″

Your explanation:
“Pretty simple. Half the couples have boys first, and stop. The rest have a girl. Of those, half have a boy second, and so on.
So suppose there are N couples. There will be N boys. There will be an “infinite” sum of girls equal to N/2 + N/4 + N/8 + … As any college math student knows, this sum adds up to N. Therefore, the proportion of boys to girls will be pretty close to 1:1, with perhaps a few more boys than girls because the sum isn’t actually infinite. ”

My explanation: the same excpect that:
”
…There will be an “infinite” sum of girls equal to N/4 + 2N/8 + 3N/16 + 4N/32… whose sum does add up to N….
”

This is why:

1/2 have a boy and stop: 0 girls
1/4 have a girl, then a boy: N/4 girls
1/8 have 2 girls, then a boy: 2*N/8 girls
1/16 have 3 girls, then a boy: 3*N/16 girls
1/32 have 4 girls, then a boy: 4*N/32 girls
…
Total: N boys and
1N 2N 3N 4N
– + — + — + — +… = ~N
4 8 16 32
