Answer:
K ∩ L = {a, e, i, n, q, t, u}
K ∪ L = {a, e, i, l, n, o, q, t, u, y}
Explanation:
Write the sets in alphabetical order
K = {a, e, i, n, o, q, t, u}
L = {a, e, i, l, n, q, t, u, y}
Set of all values that are members of both sets:
K ∩ L = {a, e, i, n, q, t, u}
Set of all values that are members of K, or L, or both:
K ∪ L = {a, e, i, l, n, o, q, t, u, y}
