Question

You have 100 people. 90 have French heritage, 80 have English heritage and 75 have Native American heritage, how many have heritage from all 3 cultures?

Answer 1

75 people because if shrink it to 20 and multiply your results be 5 then only 10
Wouldn't have any heritage. Another ten with Native American or English heritage and only 5 people with Native American so
Add that up its 25 people out of 100 it's 75 left.

Answer 2

My answer is 82. I added up 90 + 80 + 75 = 245. I then divided that by 3 because there are 3 different cultures. And the number was 81. something. So, I rounded and got 82. But I'm not sure if that's the right answer.
