Question

What are the missing values, labeled x and y, from the truth table for ~(p ∨ q) ∧ ~p?

Answer
x = F, y = T
x = T, y = F
x = F, y = F
x = T, y = T

Answer 1

@Mertsj can you exlain how i solve this one then
?

Answer 2

If they are both false then p or q is also false

Answer 3

you lost me.....im not smart you know..lol.

Answer 4

Let's say that the truth is that I am wearing black and white
Is "I am wearing red" true or false?

Answer 5

false of course.

Answer 6

What about "I am wearing blue? True or false?

Answer 7

false

Answer 8

What about "I am wearing red or blue"?

Answer 9

false...

Answer 10

Exactly if p is false (I am wearing red) and q is false (I am wearing blue) then p or q is false (I am wearing red or blue)

Answer 11

i still dontt understand how this fits in the table.....why arre there 4 rows for each column? it makes absolutely no sense

Answer 12

You are thinking of it incorrectly. Think of it as 4 columns for each row.

Answer 13

ok but what do they represent?

Answer 14

p q p ∨ q ~ (p ∨ q) ~p ~(p ∨ q) ∧ ~p
T T T F F F
That one says that if you have two true statements it is true that one or the other is true.

Answer 15

Let's say that p is: I am 10 years old.
Let's say that q is: I like dogs.
And that both of those are true.
Would it be true or false to say that I am 10 years old or I like dogs?

Answer 16

false?

Answer 17

Let's take a different example. 2+2=4, True
3+3=6, True
2+2=4 or 3+3=6, True or False?

Answer 18

true????

Answer 19

Of course. If I have two true statements then certainly one of them is true and when you use the word "or" only one of them has to be true.

Answer 20

im still not understanding what the colums and rows are for!

Answer 21

The rows are to tell whether the statement at the top of the column is true or false based upon whether p and q are true or false.

Answer 22

why are there 4 then??

Answer 23

4 rows or columns?

Answer 24

both...

Answer 25

There are 4 rows to accomodate the fact that p and q are sometimes assumed to be true and sometimes assumed to be false. In other words, they keep changing the conditions of the problem by altering the truth value of the given statements.

Answer 26

There are 4 columns because they want you to evaluate the truth of different statements.

Answer 27

im absolutely confused...........

Answer 28

i dont understand why all of the columns need to be there!

Answer 29

and i guess nobody is going to explain...:/

Answer 30

Oh... I interpreted the question differently: I interpreted it as 'given this statement, which portion of the accompanying truth table is equivalent to (values)', in which the x's are F, T, F, T that matches up with the ~q portion of the board, if you draw it out.

Answer 31

So, in other words, x is ~q for this question, and you have to figure out which values will match y, or T, F, F, T

Answer 40

its not creating the table

Answer 41

Yes, it will, you just don't know how to use it

Answer 42

well i put in this expression ~(p ∨ q) ∧ ~p

Answer 43

You can't put it in like that. You have to use the symbology that the program asks you to use.

Answer 44

nvm i got it. thank you
