(78 had two heads).....(28 had three eyes).....(21 had four arms).....(12 had two heads and three eyes).....( 9 had three eyes and four arms).....(8 had two heads and four arms).....(3 had all three unusual features)
How many had none of these unusual features?
I just tried this in my head, 5?
78+28+21=127
127-12-9-8-3=95.
