Final 10 Answer 5mp4

  • 0:00 - 0:06
    To answer this question, the very first thing we observe is that each statement implies itself.
  • 0:06 - 0:12
    So we will draw every element of the diagonal as true.
  • 0:12 - 0:19
    We also observe that "not pink" implies "green" is the same as pink or green.
  • 0:19 - 0:26
    If you do the truth table, you find that this is true either if green is true, which will be the case of B as well,
  • 0:26 - 0:34
    or if pink is true, in which case the precondition which is implied will be false, and therefore the entire statement is true.
  • 0:34 - 0:39
    So we can find out that B is exactly the same as D.
  • 0:39 - 0:44
    With that in mind, we answer the question for A to C first.
  • 0:44 - 0:52
    Pink clearly implies that pink or green is true. It doesn't imply that pink and green is true, so C is not open.
  • 0:52 - 0:56
    But because B is equivalent to D, we also check over here.
  • 0:56 - 1:05
    Pink or green doesn't imply pink, because green might be true, and doesn't imply pink and green because green might be false.
  • 1:05 - 1:12
    But it does imply D because D is exactly the same as B.
  • 1:12 - 1:18
    Pink and green implies pink. It also implies pink or green.
  • 1:18 - 1:22
    And since B is the same as D, implies D.
  • 1:22 - 1:30
    And finally, for this one over here, we just copy over B. So we get this guy and this guy over here.
