A = {1, 3, 4, 5, 7, 9}

B = {3, 5, 6, 8, 13}

C = {4, 5, 8, 15, 22}

$\bf E_{1} = A\cup B = \{1, 3, 4, 5, 6, 7, 8, 9, 13\}$  

$\bf E_{2} = A\cup C = \{1, 3, 4, 5, 7, 8, 9, 15, 22\}$  

$\bf E_{3} = B\cup C = \{3, 4, 5, 6, 8, 13, 15, 22\}$

$\bf E_{4} = A \cap B = \{3, 5\}$

$\bf E_{5} = A \cap C = \{4, 5\}$  

$\bf E_{6} = B\cap C = \{5, 8\}$

$\bf E_{7} = A \setminus B = \{1, 4, 7, 9\}$  

$\bf E_{8} = B\setminus C = \{3, 6, 13\}$  

$\bf E_{9} = C\setminus A = \{8, 15, 22\}$    

$\bf E_{10} = A\cap B\cap C = \{5\}$  

$\bf E_{11} = A\cup B\cup C = \{1, 3, 4, 5, 6, 7, 8, 9, 13, 15, 22\}$
