Answer 3

you mean it is the truth table in computer science?
I know how to write the truth table in Math only. sorry I waste your time

Answer 4

No its in math.

Answer 5

so? the array of numbers you give out seems meaningless. do you take discrete math?

Answer 6

The assignment name is Determining Logical Equivalence

Answer 7

2. Construct and complete a truth table in order to determine if the following statements are logically equivalent:

p → q and ~q → ~p

3. Explain in the box below if the statement [p ∧ (p → q)] → q is a tautology or not.

4. Explain in the box below if the statements p → q and ~q → ~p are logically equivalent or not.
These Are the Questions

Answer 8

ok I got it. wait I have to write down in a chart and then attach it for you

Answer 9

okay thank you

Answer 10

okay what does this mean?

Answer 11

YOU study it in class already , right? it the way how to make truth table and consider whether it is tautology or not

Answer 12

I didnt really Understand it at all.

Answer 13

could you see the graph i made

Answer 14

you have to give the values to p and q. and combine them. to have the completely combination, you have to give 2 values true (T) , 2 value false (F)for p and the same thing for p. but the order must be like what i send . it means for p : TTFF and for q TFTF and then combine them

Answer 15

so are p → q and ~q → ~p logically equivalent?

Answer 16

and [p ∧ (p → q)] → q is a tautology

Answer 17

ok, your professor give the value of p and q by using T and F or 1 and 0. if he give you the notation is T and F, mine is completely right, if he give you 1 and 0 then you just replace T =1 and F =0 the result is the same

Answer 18

sure, since they give out the same result in the truth table

Answer 19

Yes for second question, it is tautology. you must understand why it goes there.

Answer 20

But how am I to Explainif the statements p → q and ~q → ~p are logically equivalent
