Boolean operators are special keywords used in programming languages to perform logical operations on Boolean
values
The OR operator returns True if at least one
operand
is True.
True
The NOT operator returns the
opposite
of the operand.
What is the result of the expression `True and False` using the AND operator?
False
The expression `not True` using the NOT operator evaluates to
False
.
Which Boolean operator returns True only if both operands are True?
AND
The NOT operator returns the
opposite
of the operand.
What is the result of the expression `False or False` using the OR operator?
False
Match the Boolean operator with its description:
AND ↔️ Returns True if both operands are True
OR ↔️ Returns True if at least one operand is True
NOT ↔️ Returns the opposite of the operand
The expression `True or False` using the
OR operator
evaluates to True.
True
Which Boolean operator returns True only if both operands are True?
AND
Match the Boolean operator with its description:
AND ↔️ Returns True if both operands are True
OR ↔️ Returns True if at least one operand is True
NOT ↔️ Returns the opposite of the operand
The expression `True or False` using the
OR operator
evaluates to True.
True
Understanding Boolean operators is crucial for writing
conditional statements
.
True
The OR operator returns True if at least one of the operands is True.
True
Order the following Boolean operators based on their precedence (highest to lowest).
1️⃣ NOT
2️⃣ AND
3️⃣ OR
The expression `not False` using the NOT operator evaluates to
True
.
True
What is the result of the expression `True and False` using the AND operator?
False
The expression `not True` using the NOT operator evaluates to
False
.
The AND operator returns True if at least one operand is True.
False
The expression `False or True` using the
OR operator
evaluates to True.
True
Boolean operators help control the flow of a program by evaluating
logical
expressions.
True
Which Boolean operator returns True if both operands are True?
AND
The NOT operator returns the
opposite
of the operand.
The `or` operator returns True if both operands are False.
False
Match the Boolean operator with its description:
AND ↔️ Returns True if both operands are True
OR ↔️ Returns True if at least one operand is True
NOT ↔️ Returns the opposite of the operand
The `or` operator returns True if at least one operand is
True
The OR operator returns True if at least one operand is
True
The OR operator returns False only when both
operands
are False.
True
The OR operator returns True only if both operands are True.
False
Under what condition does the AND operator return True?
Both operands are True
The AND operator returns True if
both
operands are
True
The NOT operator returns True if the operand is
False
The AND operator returns False if at least one operand is
False
Order the results of the AND operator truth table when Operand 1 is True:
1️⃣ True if Operand 2 is True
2️⃣ False if Operand 2 is False
Order the results of the OR operator truth table when Operand 1 is True:
1️⃣ True if Operand 2 is True
2️⃣ True if Operand 2 is False
The NOT operator returns False if the operand is
True
The AND truth table returns True only if both operands are
True
What does the NOT truth table return if the operand is True?
False
True and not
False
results in True.
True
