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

O {6, 12, 18, 21, 24, 27}
O {1, 5, 7, 11, 13, 17}
To find the intersection of two sets R and D, denoted by R ∩ D, we need to find the elements that are common to both sets.
Given that R = {1, 3, 5, 7, 9, 11, 13, 15, 17} and D = {3, 6, 9, 12, 15, 18, 21, 24, 27}, we can find R ∩ D as follows:
{3, 9, 15}
Therefore, the correct answer is {3, 9, 15}.
To find the intersection of sets R and D, denoted as R ∩ D or RnD, you need to find the elements that are common to both sets.
In this case, set R = {1, 3, 5, 7, 9, 11, 13, 15, 17} and set D = {3, 6, 9, 12, 15, 18, 21, 24, 27}.
To find the intersection, you compare the elements in both sets and find the ones that are present in both sets. The common elements in R and D are 3, 9, and 15.
Therefore, the answer is {3, 9, 15}.
