In a class of 30 kindergartners 12 wet their pants today 17 pick their nose 9 did neither how many did both

0. All you do is add up all the number except 30, u should get 38, whichh means it was 0 students who did neither Hope this helps!

Okay best guess is that 12 wet their pants TODAY, but not every day and 17 kids just regularly pick their nose meaning we subtract 9 from the 12 kids giving us 3 now we add those kids to the group of kids that pick their nose giving us 20 and subtracted gives us 10 kids

Hnmmmn not sure
