To simplify the given Boolean expression:

$A'B'C' + A'C'(B) + AD + ABC'D'$

Step-by-step simplification:

1. Group terms: $A'B'C' + A'C'B + AD + ABC'D'$

2. Combine like terms for the first two terms:

   • $A'B'C' + A'C'B$
   • Factor out $A'C'$: $A'C'(B' + B) + AD + ABC'D'$
   • Since $B' + B = 1$: $A'C' + AD + ABC'D'$

3. Final simplified expression: $A'C' + AD + ABC'D'$

Thus, the simplified Boolean expression is: $A'C' + AD + ABC'D'$
