| I | Item carries a bonus point. |
(In all the above cases, 1 indicates yes and 0 indicates no.)
Output: X[1 indicates bonus point awarded, 0 indicates bonus point not awarded for all cases]
Draw the truth table for the inputs and outputs given above and write the POS expression for X(C, A, F, I).
Verify the following expression by using the truth table:
(A ☉ B)' = A ⊕ B
Verify if the following proposition is valid using the truth table:
(X ∧ Y) =>Z = (Y => Z) ∧ (X => Y).
