5:50 as someone who likes maths recreationally, It doesn't exactly add up to 170%, because the people who are in the first set (people who like with their elbows) definetely aren't in the second set (people who can't like with their elbows), but not necessairly people who are not in set B are in set A, they could be able to, but do not like with their elbows. So imagine there is a huge circle (the universal set, everyone), a smaller circle (set A) inside of it, the rest of it, U - (U-A), then is separeted between the ones in set B, and the others, wich are those that can like with their elbows, but choose not to (set C).
Anyways, there is no way that set B has 80% of U, and set A has 90% of U, because they both have to add to U (and we still have to count the set C) But you can't just add these percentages
