mathstudent55 · Answer

Can you list the numbers from 1 to 12 that are divisible by 6?

anonymous · Answer

6 and 12? @mathstudent55

mathstudent55 · Answer

Correct. That means that set D = {6, 12}

mathstudent55 · Answer

Do you know what the intersection of two sets is?

mathstudent55 · Answer

C = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}
D = {6, 12}
C ∩ D = {set of elements that are both in set C and set D}
