The Maths Thread

Agreed, but the statistical probability that it is exactly 50/50 is minuscule, without having to factor in the other variables.

Yes you’re correct. It has to be wrong because the global fertility rate is 2.3.

If half the babies didn’t make it past day one then we’d be well below replacement rate and the population of the earth would be decreasing… which it demonstrably is not even close to doing.

that can't be right, can it?

if a woman has 8 babies in her lifetime and half of them die in the day they are born she still has 4, which is above the replacement rate.
 
and yet you both continued replying on the subject.

what are the chances of being out on a subject while still being in?

I operate on quantum probabilities so I can exist in a superposition of being in and out until somebody observes me.

8 babies is not the average per woman though. The average is 2.3. So if half of them die you’re left with 1.15 babies per woman. The replacement rate needed to maintain a population is about 2.1.
 
I replied to a poster that posts well on many subjects.

I‘m out from your silly question that seems to be more about you wanting to bait posters than actually debate.
i'm honestly not baiting anyone, just passing time that's all, like you.
don't go taking me too seriously, blue.
it was a wine-drinking question, they are often silly questions but worth asking.

I’ll set you a wine drinking question, how did the universe start, or to put it another way what was there before there was nothing and did nothing ever exist?

i read somewhere that we are close.
a quick google check says we are heading that way.
e.g...

"While the global population is still increasing in absolute numbers, population growth peaked decades ago. In the chart, we see the global population growth rate per year. This is based on historical UN estimates and its medium projection to 2100. Global population growth peaked in the 1960s at over 2% per year."
