Let U = {1, 2, 3, 4, 5, 6, 7}, A = {1, 2, 3, 4}, B = {1, 2, 5, 6}, and C = {3, 5, 7}. List all the members of the given set. (Enter your answers as a comma-separated list.)
I suspect you have missed out part of the question, such as:
a) A∪B
b) A∩B
...
etc.
Which is/are the "given set"?
To find the members of the given set, we need to combine the members of sets A, B, and C.
Set A has members 1, 2, 3, and 4.
Set B has members 1, 2, 5, and 6.
Set C has members 3, 5, and 7.
Combining all the members from these sets gives us:
1, 2, 3, 4, 5, 6, 7.
Therefore, the members of the given set are 1, 2, 3, 4, 5, 6, and 7.
A) {1,2,3,4,5,6}
B) {2}
