Question

@friedch1cken
If C = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12} and D = {numbers divisible by 2 from 1 to 10}, what is CD?

{2, 4, 6, 8, 10}

{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}

{1, 3, 5, 7, 9, 11}

{2, 4, 6, 8, 10, 12}

Answer 1

I assume CD means C and D.
C = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12}
D = {numbers divisible by 2 from 1 to 10}
All numbers divisible by 2 are even numbers. So we need to find the even numbers from 1 to 10. So,
D = {2, 4, 6, 8, 10}
C and D contains all the numbers that appear in both sets.
C and D = {2, 4, 6, 8, 10}
Does that make sense?

Answer 2

yes !!!!
