Question

The complement of set M is:

{6}
{4, 6, 7}
{2, 5, 8}
{2, 5, 6, 8}

Answer 1

The complement of a set is everything that is NOT in the set. Think of it as the complete opposite. 

The numbers in circle M are: 9, 3, 4, 7

The other numbers not in this circle are: 2, 5, 8, 6

Rearrange numbers in ascending order: 2, 5, 6, 8

So the answer is choice D. 

Answer 2

Answer:

D. {2, 5, 6, 8}.

Step-by-step explanation:

We are given that,

The points in the set M are {3, 4, 7, 9}.

Now, 'the complement of the set means the points lying outside the set'.

So, from the figure, we see that,

Points which are outside of the set M are {2, 5, 6, 8}.

Hence, the complement of the set M is the set {2, 5, 6, 8}.
