Here,

A = {0,2,4,6,8,10}

B = {0,1,2,3,4,5,6}

C = {4,5,6,7,8,9,10}


So,

a) "A\\cap B\\cap C= \\{4,6\\}"


b)"A\\cup B\\cup C =\\{0,1,2,3,4,5,6,7,8,9,10\\}"


c)"(A\\cup B)\\cap C"

"A\\cup B =\\{0,1,2,3,4,5,6,8,10\\}\\\\So,\\ \\ (A\\cup B)\\cap C=\\{4,5,6,8,10\\}"


d) "(A\\cap B)\\cup C"

"A\\cap B = \\{0,2,4,6\\}"

So, "(A\\cap B)\\cup C=\\{0,2,4,5,6,7,8,9,10\\}"
