Consider the following expressions
1. Y = ƒ (A, B, C, D) = ∑ (1, 2, 4, 7, 8, 11, 13, 14)
2. Y = ƒ (A, B, C, D) = ∑ (3, 5, 7, 10, 11, 12, 13, 14)
3. Y = ƒ (A, B, C, D) = ∑ (0, 3, 5, 6, 9, 10, 12, 15)
4. Y = ƒ (A, B, C, D) = ∑ (0, 1, 2, 4, 5, 8, 9, 15)
Which of these expressions are equivalent to the expression Y = A ⊕ B ⊕ C ⊕ D?
