If A={2,4,6,8,10} B={3,4,5,6,7}
So A-B=?
{2,4,5,6,7}
{2,6,8,10}
{2,8,10}
{2,3,4,5,6,7,8,10}
If universal set U = {1, 2, 3, 4, 5, 6,7, 8, 9, 10}, A = {2, 4, 6, 8}, then Ac is:
In the following, state whether A = B or not :
(i) A = {a, b, c, d} B = {d, c, b, a}
(ii) A = {4, 8, 12, 16} B = {8, 4, 16, 18}
(iii) A = {2, 4, 6, 8, 10} B = {x : x is a positive even integer and x≤10
(iv) A = {x : x is a multiple of 10} B = {10, 15, 20, 25, 30, ...........}
