1 out of 4,900,000.
This is considered a real woman with a penis. If you want a vagina it's like...
X = 40
40 represents the number of years most men are virgins
4,900,000(x)
without a calculator
5,000,000(40) = 200,000,000
still have to figure out the other missing area
100,000(40) = 4,000,000
so some more multiplying.
200,000,000(4,000,000)
That's 1 out of 200,000,000(4,000,000) that are biological women. My statistics might be off by one or two.
