Explanation / Answer

c) Four year colleges that offer a computer engineering degree but neither a liberal arts nor a nursing degree = n(offering computer engineering degree) - [ n(offering computer engineering and liberal arts degree) + n(offering computer engineering and nursing degree) - n(offering all 3) ] = 110- [25+87-21] = 19

d) Four year colleges that offer all 3 = 21
