## anonymous 3 years ago 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

1. anonymous

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

2. anonymous

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

3. anonymous

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

4. anonymous

then what?

5. anonymous

Not q or r then p

6. anonymous

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

7. anonymous

Well I am not familiar with those symbols

8. anonymous

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

9. anonymous

hmmmmm let me think abt this one

10. anonymous

that would be splendid

11. anonymous

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

12. anonymous

mmhmm

13. anonymous

(p^~q)->r

14. anonymous

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

15. anonymous

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

16. anonymous

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

17. anonymous

ya so then its that

18. anonymous

question is...why?

19. anonymous

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

20. anonymous

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

21. anonymous

nope I changed what r symblizes

22. anonymous

oh. so it's going to be (p ^ ~q) -> ~r still i ask..why?

23. anonymous

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

24. anonymous

main part is (p ^ ~q)

25. anonymous

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

26. anonymous

i just said what was confusing me....

27. anonymous

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

28. anonymous

^ means and yes?

29. anonymous

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

30. anonymous

hmm so 18 andnot accompanied by parent implies no watch?

31. anonymous

Correct

32. bahrom7893

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

33. anonymous

thanks

34. anonymous

35. bahrom7893

18 implies watch

36. anonymous

37. bahrom7893

under 18 implies music chatbox

38. anonymous

HAHAHAH LOL

39. anonymous

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