suppose R ={1, 3, 5, 7, 9, 11, 15, 17} and D= {3, 6, 9, 12, 15, 18, 21, 24, 27}. what is RnD
I assume you meant : R ∩ D
What numbers do you see that appear in both R AND D
list them in set notation.
If by that "n" you mean ∩, it just means the datasets of the values of R AND D.
To find the intersection of two sets R and D (denoted as R ∩ D or RnD), we need to identify the elements that are common to both sets.
Given that R = {1, 3, 5, 7, 9, 11, 15, 17} and D = {3, 6, 9, 12, 15, 18, 21, 24, 27}, we can compare the elements in both sets and find their intersection:
1. Start by comparing the first element of R, which is 1, with all the elements of set D.
2. Move on to the next element in set R, which is 3. Since 3 is present in both sets, we include it in the intersection.
3. Continue this process for each element in set R.
4. After comparing all the elements, the intersection of R and D is {3, 9, 15}.
Therefore, RnD = {3, 9, 15}.
