Answer 1

Answer:-

• A ∩ (B-C)

x ∈ A and x ∈ (B-C)

x ∈ A, and x ∈ B and x ∉ C

x ∈ (A and B) but x ∉ (A and C)

x ∈ (A∩B) - (A∩C)

A ∩(B-C) ⊂ (A∩B) - (A∩C) equation(1)

• (A∩B) - (A∩C)

y ∈(A∩B) but y ∉ (A∩C)

y ∈A, and y ∈ B but y ∈ A and y ∉ C

y ∈ A ∩(B-C)

(A∩B) - (A∩C) ⊂ A ∩(B-C) equation(2)

From Equation (1) and (2)

A ∩(B-C) = (A∩B) - (A∩C)
