Q-P:

Answer 1

S = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14}
P = {0,1,2,3,4,5,6,7}
Q = {5,6,7,8,9,10,11,12,13,14}

P n Q = {5,6,7}
P U Q = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14} = S
P - Q = {0,1,2,3,4}
Q - P = {8,9,10,11,12,13,14}

Answer 2

S = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}
P = {0, 1, 2, 3, 4, 5, 6, 7}
Q = {5, 6, 7, 8, 9, 10, 11, 12, 13, 14}

P n Q = {5, 6, 7}
P u Q = {0,1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}
P - Q = {0, 1, 2, 3, 4}
Q - P = {8, 9, 10, 11, 12, 13, 14}
