How can i wire the 6-DIP switch to the HD74LS283P Full-adder IC and a LED to the chip so that whenever >3(4 and above) dip switch is ON(high) my led will light up?
I dont know if it is possible to do with 1 chip but from my suggested answer, it would require as least 2 adder chip? I spend like few hour wiring up with some combinations/ways and i still cant get it.
Here an aided diagram :

and here is the datasheet of the chip being used:
