The sets {NAND}, {NOR, NOT}, and {AND, OR} are logically complete. A set of gates is considered logically complete if it can be used to implement any truth table.
Let's analyze each set:
{NAND}: NAND gates are known to be logically complete. This means that any logic circuit can be constructed using only NAND gates. By combining NAND gates in various configurations, we can implement all other logical functions such as AND, OR, NOT, and XOR.
{NOR, NOT}: The set {NOR, NOT} is also logically complete. NOR gates are universal gates, which means they can be used to implement any logical function. By combining NOR gates and using NOT gates, we can construct circuits that represent any truth table.
{AND, OR}: The set {AND, OR} is logically complete as well. Both AND and OR gates are considered to be universal gates. By using these two gates and potentially adding NOT gates, we can create circuits that can represent any truth table.
Therefore, the sets {NAND}, {NOR, NOT}, and {AND, OR} are all logically complete, as they allow for the implementation of any truth table.

>>> A = [21, 'dog', 'red'] >>> B = [35, 'cat', 'blue'] >>> C = [12, 'fish', green'] >>> E = [A, B, C] What is the value of E1 2
The value of E[1][2] is 'blue'
How to determine the value of E?The code segment is given as:
A = [21, 'dog', 'red']
B = [35, 'cat', 'blue']
C = [12, 'fish', 'green']
E = [A, B, C]
The above code segment is written in Python, and the lists A, B and C are merged to form list E
This means that list E would be a two-dimensional list.
So, the value of E is [[21, 'dog', 'red'], [35, 'cat', 'blue'], [12, 'fish', 'green']]
Rewrite as:
E = [[21, 'dog', 'red'],
[35, 'cat', 'blue'],
[12, 'fish', 'green']]
The element at E[1][2] is the element at the second row and the third column.
This element is 'blue'
