Step 1: Simplification of Expression.
The given expression is \( F(X,Y) = X Y + X Y' + X Y \). Observe that \( X Y + X Y = X \), so the expression simplifies to:
\[
F(X,Y) = X + X Y'
\]
Step 2: Using Consensus Theorem.
Now, apply the consensus theorem, which states that \( X + X Y' = X + Y \). Thus, the simplified expression is:
\[
F(X,Y) = X + Y
\]
Step 3: Conclusion.
The output of the minimized expression is \( X + Y \), so the correct answer is (B).
Find the least upper bound and greatest lower bound of \( S = \{X, Y, Z\} \) if they exist, of the poset whose Hasse diagram is shown below:
Suppose \( D_1 = (S_1, \Sigma, q_1, F_1, \delta_1) \) and \( D_2 = (S_2, \Sigma, q_2, F_2, \delta_2) \) are finite automata accepting languages \( L_1 \) and \( L_2 \), respectively. Then, which of the following languages will also be accepted by the finite automata:
(A) \( L_1 \cup L_2 \)
(B) \( L_1 \cap L_2 \)
(C) \( L_1 - L_2 \)
