10 and 20 are common to both set A and set C.
{10, 20} would be the correct choice.
{10, 20} would be the correct choice.
Let U = {5, 10, 15, 20, 25, 30, 35, 40} A = {5, 10, 15, 20} B = {25, 30, 35, 40} C = {10, 20, 30, 40}. Find A ⋂ C. (Points :1) {5, 15, 30, 40} Ø {5, 10, 15, 20, 30, 40} {10, 20}?
