Approximately 12%
So 12% of 7,000,000,000 (approx)
7,000,000,000/100 = 70,000,000
70,000,000 x 12= 840,000,000 left handers (less than the population of 2 of the world's countries- so not a lot really)
The ratio of left handed people to right handed people is 1:10 and there are around 6,692,030,277 in the world, so that means that around 6 022 827 249 right handed people.
96% of people are right handed
Approximately 60-65% of hockey players are right-handed, meaning they shoot the puck with their right hand on the lower part of the stick. The remaining 35-40% are left-handed shooters.
The ratio of left handed people to right handed people is 1:10 and there are around 6,692,030,277 in the world, so that means that around 6 022 827 249 right handed people.

There is no definitive answer as sexual orientation and handedness are independent traits. Studies have shown that handedness is not significantly correlated with sexual orientation.
because of genetics
The same number of years as right-handed people can live to.
They do not. On average, right handed people live 9 years longer than them.
I'm not 100% sure about this, but I have been doing a report on asymmetries betweent the right and left hands and the differences in these asymmetries between right- and left-handers, and from the information I have come across the 1 to 9 ratio seems to be pretty well accepted. (10% left-handed / 90% right-handed). Please correct me if you have more specific or up to date info. I believe ur right about that and of that 10%, 70% are males and 30% are females which means that 90% of the world is right-handed and 10% is left, 7% of the world is left-handed males and 3% is left-handed females. I believe you may be wrong because if 10% of people are left handed then 90% of people are right handed then how many people are ambidextrious? ^The amount of ambidextrous people is assumed to be negligible in this case.

A couple of reasons- evolutionarily, it was easier for right-handed people to survive. Also, many people in older generations who were left-handed were punished for favoring that hand and learned to adapt to using their right. Lefties also die younger- no one know why though.
