Let A = {2, 4, 6, 8,10} , B = (2, 4, 8, 10}, and C = {2, 4, 6, 9}
Complete the following
9 ∈ ___
Enter A, B or C for solution
I think its A = {2, 4, 6, 8,10}
Why would you think that?
Do you see a 9 in A ??
Oh ya you right so its C my bad
To check whether 9 is an element in a set A, B, or C, you need to compare 9 with each element in the set.
For set A = {2, 4, 6, 8, 10}, since 9 is not one of the elements in the set, you can conclude that 9 is not an element of set A.
For set B = (2, 4, 8, 10}, you made a small mistake in the notation. The correct notation for set B is B = {2, 4, 8, 10}. Again, since 9 is not an element in set B, you can conclude that 9 is not an element of set B.
For set C = {2, 4, 6, 9}, you can see that 9 is indeed one of the elements in the set. Therefore, you can conclude that 9 is an element of set C.
So, the correct answer is C = {2, 4, 6, 9}.
