Question

Use an ordinary truth table to answer the following problems. Construct the truth table as per the instructions in the textbook.

Statement 1A
Given the following statement:
(N ⊃ K) ≡ (K ⊃ N)
The truth table for Statement 1A has how many lines?
Group of answer choices
A) Six.
B) Four.
C) Two.
D) Eight.
E) Nine.

Answer 1

The truth table for Statement 1A has four lines.

Step-by-step explanation:

To determine the number of lines in the truth table for the given statement, we need to count the number of possible combinations of truth values for the variables involved. In this case, there are 2 variables, N and K. Each variable can take on 2 possible truth values, true (T) or false (F). So, the total number of possible combinations is 2 * 2 = 4. Therefore, the truth table for Statement 1A has four lines.
