If C = {integers divisible by 2 from 1 to 25} and D = {integers divisible by 6 from 1 to 30}, what is C ∩ D?

{ }

{2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 30}

{6, 12, 18, 24, 30}

{6, 12, 18, 24}

anonymous · Answer

find the common integer in both C and D.that is the interection for C and D

anonymous · Answer

Write out all the elements in C and all the elements in D, and then the new set is all of the elements in both C AND D.

anonymous · Answer

C?

anonymous · Answer

write C and D
find out the elements common( present in both) 
that is = C (intersection) D

anonymous · Answer

Wait.. huh?.

anonymous · Answer

Oh B?

anonymous · Answer

All those numbers fit both C and D.

anonymous · Answer

{2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 30} = C 
 {6, 12, 18, 24, 30} = D

which is common in both (6, 12 , 18, 24, 30)
C∩D
