The set S represents even numbers from 2 to 30.
S = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30}

The set C represents multiples of 3 from 3 to 30.
C = {3, 6, 9, 12, 15, 18, 21, 24, 27, 30}

How many elements are in the set ?

Question

The set S represents even numbers from 2 to 30.
S = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30}

The set C represents multiples of 3 from 3 to 30.
C = {3, 6, 9, 12, 15, 18, 21, 24, 27, 30}

How many elements are in the set ?

directrix · Answer

Do you want to find the number of elements in each separate set, the union of the two sets, or perhaps the intersection of the sets?

anonymous · Answer

both sets

anonymous · Answer

no wait intersection

directrix · Answer

Set S has 15 elements.

Seet C has 10 elements.

directrix · Answer

S intersect C has 5 elements, all multiples of both 2 and 3.

{6, 12, 18, 24, 30}

anonymous · Answer

Intersect of S and C is all even numbers from C
= { 6, 12, 18, 24, 30}  --> 5 elements
