Suppose R = {1, 3, 5, 7, 9, 11, 13, 15, 17} and D = {3, 6, 9, 12, 15, 18, 21, 24, 27}. What is ?

{1, 3, 5, 6, 7, 9, 11, 12, 13, 15, 17, 18, 21, 24, 27}

{6, 12, 18, 21, 24, 27}
The intersection of sets R and D is {3, 15}.
To find the intersection of sets R and D, you should find the elements that are present in both sets.
Step 1: Compare each element in set R with each element in set D.
- element 1 in set R is not in set D
- element 3 in set R is in set D
- element 5 in set R is not in set D
- element 7 in set R is not in set D
- element 9 in set R is in set D
- element 11 in set R is not in set D
- element 13 in set R is not in set D
- element 15 in set R is in set D
- element 17 in set R is not in set D
Step 2: Write down the elements that are present in both sets.
The elements that are present in both sets R and D are 3, 9, and 15.
Therefore, the correct answer is {3, 9, 15}.
To determine the answer, we need to find the set of elements that are common to both sets R and D.
To do this, we can visually compare the two sets and identify the elements that are present in both.
Set R contains the elements {1, 3, 5, 7, 9, 11, 13, 15, 17}, and set D contains the elements {3, 6, 9, 12, 15, 18, 21, 24, 27}.
By comparing the two sets, we can see that the elements {3, 9, 15} are present in both sets.
Therefore, the answer is {3, 9, 15}.
