Given: J = { p, a, n, d, e, m, i, c}

K = { c, a, m, e }

L = { }

Find: J ∪ K

• J ∪ K = { p, a, n, d, e, m, i, c }

• J ∪ K = { c, a, m, e}

• J ∪ K = { p, n, d, i }

• J ∪ K = { }

If every element in set A is also in set B, then...

• A is a subset of B
• B is a subset of A
• A = B
• A and B are disjoint
