volume_muteAn ordered pair (1, 2) = (2, 1)
True
False
Correct Answer
False
Explanation
The ordered pair consisting of the element 1 and 2, in which 1 is the first element will be written as (1, 2), whereas the ordered pair consisting of the elements 1 and
2 in which 2 is the first element will be written as (2, 1). Obviously, then (1, 2) ≠ (2, 1).
Note: in elementary set theory, order of elements in a set is immaterial
