True or True and False or False
Applying logical operators:
Evaluate and first (higher precedence):
True and False evaluates to False.
The expression now becomes:
True or False or False.
Evaluate or from left to right:
True or False evaluates to True.
True or False evaluates to True.
True and False
Since the AND operator requires both conditions to be True for the whole expression to be True, and one of them is False, the overall expression evaluates to False.
Therefore, the value assigned to
𝑥
x will be False, making the correct answer C (False).
So, the provided answer key is incorrect; it should be C (False) instead of D (True).
Let's break down the expression:
x = y < z or (z > y and y > z) or z < y
Now, we evaluate the sub-expressions:
y < z evaluates to 1 < 2, which is True.
z > y evaluates to 2 > 1, which is True.
y > z evaluates to 1 > 2, which is False.
z < y evaluates to 2 < 1, which is False.
So, plugging these values into the expression, we get:
x = True or (True and False) or False
Evaluate the and expression:
True and False is False.
Now the expression becomes:
x = True or False or False
Finally, evaluate the or expressions:
True or False is True.
So, the value assigned to x will be True.
The correct answer is:
D. True
