suppose C is subset of D and D is a subset of C.
a) If n(c)=5, find n(D)
b) what other relationship exists between sets C and D?
You can put this solution on YOUR website! Remember, if C is subset of D and D is a subset of C, then sets C and D are the same sets (draw a picture if you're unsure). In notation form, this looks like:
If and , then
a) So n(C)=5 also tells us that n(D)=5 (ie the number of elements in sets C and D is 5) since C=D
