If, A = {𝑐, 𝑑, 𝑏, ℎ} and B = {𝑚, 𝑝, 𝑓, ℎ} then A ∪ B = ____ ?

{𝑐, 𝑑, 𝑏, ℎ, 𝑝, ℎ}

{𝑐, 𝑑, 𝑏, ℎ}

{𝑐, 𝑑, 𝑏, ℎ, 𝑚, 𝑝, 𝑓}

None of these

The union of two sets A and B, denoted as A ∪ B, is the set of all elements that are in A, in B, or in both.

A = {𝑐, 𝑑, 𝑏, ℎ} and B = {𝑚, 𝑝, 𝑓, ℎ}

A ∪ B = {𝑐, 𝑑, 𝑏, ℎ, 𝑚, 𝑝, 𝑓}
