Of 50 students surveyed. 30 day they like algebra, 21 say they like trigonometry, and 8 say they like both. How many students do not like either algebra or trigonometry? A 7 B 0 C 12 D1
It is A because 30+21 is 51 then subtract 8 from that which is 43 then subtract 43 from 50 it is 7
Does that make sense?
Hahahha, that is the right answer. Thank you:)
Haha? Your Welcome:)
