Given A = [true false true], B = [false true true], what is A & B?
A & B results in [false false true] because logical AND is true only where both A and B are true.

What is the result of ~true in MATLAB?
✗ Incorrect
The ~ operator inverts true to false.
Which operator performs element-wise logical OR in MATLAB?
✗ Incorrect
The | operator performs element-wise logical OR.
If A = [1 0 1] and B = [0 1 1], what is A & B in MATLAB?
✗ Incorrect
Logical AND returns true only where both elements are true (1).
What does the expression A | B return if A and B are logical arrays?
✗ Incorrect
The | operator returns the logical OR of A and B.
Which operator would you use to invert a logical array in MATLAB?
✗ Incorrect
The ~ operator inverts logical values.
