Will you help me find the following sets please... I am a little confused

U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, A = {2, 3, 5}, B = {2, 4, 6, 8}, and C = {1, 3, 5, 7, 9}

1. = _______________________ 5. B U C = _________________________

1. U B = ____________________ 6. A (B U C) = ______________________

1. A B = ____________________ 7. (A B) U C = ______________________

1. B = ____________________ 8. A C = ___________________________

9. A C = _______________________ 10. B C = __________________ 11. n(C) = _________
