If A is a subset of C and B is also a subset of C, then is A union B a subset of C also (subset, not a proper subset)? Intuitively, I'd say no, but I could be wrong..?

Best ResponseYou've already chosen the best response.1dw:1340779359345:dw As you see, A and B are subsets of C. Their union is the "shaded area". dw:1340779385082:dw So yes, their union is still a subset of C! All points belong within it.
