Answer:
B ∪ C={a, b, e, g, h, l, m, r, t, y}
Explanation:
Given B = {a, l, g, e, b, r} and C = {m, y, t, h}
B ∪ C means B union C
To find the union of B and C we combine all the data in both sets
When the data is repeating then we put it only once
Put all the characters inside B and C in single group to get the union of B and C
B ∪ C={a, l, g, e, b, r,m, y, t, h}
B ∪ C={a, b, e, g, h, l, m, r, t, y}
