12. Suppose U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} is the universal set and M = {7, 8, 9,10}. What is M'?
A.{1, 2, 3, 4, 5, 6}
B. {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
C.cannot be determined
D.{7, 8, 9, 10}
M' is everything in U that is not in M.
So, which elements are those?
so A
To find the complement of a set, denoted by A', you need to find all the elements that are in the universal set but not in the given set.
Given that the universal set U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} and the set M = {7, 8, 9, 10}, we need to find M'.
To find M', we need to remove all the elements in M from U.
So, the elements in M are {7, 8, 9, 10}. Removing these elements from U, we get M' = {1, 2, 3, 4, 5, 6}.
Therefore, the correct answer is option A. {1, 2, 3, 4, 5, 6}.
