The given expression is a Boolean algebra expression, which can be simplified. Let's start by simplifying it step by step using Boolean algebra rules such as combining like terms and applying identities.

Expression:

$Y = A′B′C′D + A′BC′D + A′B′CD′ + A′BCD + AB′C′D′ + AB′CD + ABC′D + ABCD′$

Step 1: Group similar terms

Group the terms where common factors can be found:

1. $A′B′C′D + A′BC′D$

   • Common factor: $A′C′D$
   • Simplified to: $A′C′D(B′ + B) = A′C′D$ (since $B′ + B = 1$)

2. $A′B′CD′ + A′BCD$

   • Common factor: $A′D′B′C + A′BC = A′D′(B′C + BC)$
   • Simplified to: $A′D′C$

3. $AB′C′D′ + AB′CD$

   • Common factor: $AB′D′(C′ + C) = AB′D′$

4. $ABC′D + ABCD′$

   • Common factor: $AB(C′D + CD′) = AB(D(C′ + D′) = ABC′D$

Step 2: Combine simplified terms:

$Y = A′C′D + A′D′C + AB′D′ + ABC′D$

Step 3: Simplify further:

Group terms that can be further combined:

1. $A′C′D$ and $A′D′C$

   • Can't be combined any further directly.

2. $AB′D′$

   • Remains as is.

3. $ABC′D$

   • Remains as is.

Since the above terms have different variables, they cannot be further simplified.

Final Simplified Expression:

$Y = A′C′D + A′D′C + AB′D′ + ABC′D$

This is the simplified Boolean expression.
