Question

Translate the statement "you cannot watch the movie if you are under 18 years old unless you are accompanied by your parents" into a logical expression

Answer 1

If u r >=18 or Accompanied by your parents then
U can watch movie

Answer 2

that's not really a logical expression....

Answer 3

i assume this will be the start:

p: you can watch the movie
q: you are under 18
r: you are accompanied by your paretns

Answer 4

then what?

Answer 5

Not q or r then p

Answer 6

\(r \wedge q) \rightarrow p\)?

Answer 7

Well I am not familiar with those symbols

Answer 8

hmm seems it should be \[(q \wedge \neg r) \rightarrow \neg p\]
why?

Answer 9

hmmmmm let me think abt this one

Answer 10

that would be splendid

Answer 11

if you are under 18 years old and not accompanied by a parent then you can not watch the movie

p=under 18 years old
q=accompanied by a parent
r=unable to watch movie

Answer 12

mmhmm

Answer 13

(p^~q)->r

Answer 14

should be (p^~q) -> ~r

Answer 15

give me one more sec
I doubt its (p^q)->r

Answer 16

yeah...i just said what it is supposed to be

Answer 17

ya so then its that

Answer 18

question is...why?

Answer 19

if you are under 18 years old and not accompanied by a parent then you can not watch the movie
p=if you are under 18 years old
q=accompanied by a parent
r= can watch movie

Answer 20

....you're just repeating yourself...

Answer 21

nope I changed what r symblizes

Answer 22

oh. so it's going to be (p ^ ~q) -> ~r

still i ask..why?

Answer 23

which part is confusing?
Ok for starters I switched around the order of the sentence. I put the result which was cannot watch movie at the end of the sentence
So basically i rearranged the sentence so that the 2 conditions are in the beginning
unless accompanied by an adult is another way of saying not accompanied by an adult

Answer 24

main part is (p ^ ~q)

Answer 25

I am not sure what is confusing you. The hard part is rearranging the sentence

Answer 26

i just said what was confusing me....

Answer 27

okkk we need 2 conditions in order to not be able to go to the movie
1) under 18 years of age
2) not accompanied by a parent

Under 18 years of age is in a postive form p=under 18 years of age
Not accompanied by a parent is in a negative form ~q= not accompanied by parent
q=accompanied by parent

Answer 28

^ means and yes?

Answer 29

So if you are under 18 years of age and NOT accompanied by a parent Then you can NOT watch the movie
(p^~q)=~r
^=and

Answer 30

hmm so 18 andnot accompanied by parent implies no watch?

Answer 31

Correct

Answer 32

Actually no, under 18 and not accompanied implies no watch.

Answer 33

Answer 34

Answer 35

18 implies watch

Answer 36

under 18 implies bad dreams

Answer 37

under 18 implies music chatbox

Answer 38

Answer 39

What happens if you frequent music chat when you are older than 18?
