Answer: The elements that are NOT in Set M are 2, 5, 6 and 8.
Step-by-step explanation: We are given the Venn-diagram in the figure.
We are to find all the elements that are NOT in set M.
That is, we are to find the complement of M, given by
[tex]M^\prime=U-M.[/tex]
Now, the elements in the universal set U and the set M are
M = {3, 4, 7, 9} and U = {2, 3, 4, 5, 6, 7, 8, 9}.
Therefore, we get
[tex]M^\prime=U-M=\{2,3,4,5,6,7,8,9\}-\{3,4,7,9\}=\{2,5,6,8\}.[/tex]
Thus, the elements that are NOT in Set M are 2, 5, 6 and 8.
