Determine the value of the Boolean expression AB + AB .

Determine the value of the Boolean expression

AB + \overline{AB}

.

Options

A $1$
B $B$
C $0$
D $A$

Correct answer

A. $1$

Step-by-step solution

Let

X = AB

.

The given Boolean expression can be written as

X + \overline{X}

.

According to the Boolean identity,

X + \overline{X} = 1

for any Boolean variable

X

.

Therefore,

AB + \overline{AB} = 1

.
