Reason for Change

 * $$A \wedge B \wedge \neg D \vee A \wedge \neg B \wedge D \vee \neg A \wedge B \wedge D $$

Or
 * $$A.B. \bar {D} + A. \bar {B} .D + \bar {A} .B.D $$

The above boolean is wrong if we look at the last entry in the table. The above expression gives 1.1.0 +1.0.1+ 0.1.1= 0 which is wrong. This means we should add + A.B.D to it. But it then reduces to A.B + A.D + B.D.
