Could someone please help me with this question? Anyone? :c
Read the two statements shown below.
If the weather is not cold, Meg will go swimming.
The weather is cold, or Meg will go swimming.
Create truth tables for the logical form of the two statements (not to be submitted). Use the truth tables to determine whether the two statements are logically equivalent. Justify your answer.

Best ResponseYou've already chosen the best response.1not sure what you mean by "Thats with all the odd symbols", but go ahead and make one and post it here so we can see it

Best ResponseYou've already chosen the best response.0No, because she can go swimming and the weather can be cold. The first statement only guarantees swimming if the weather isn't cold. It doesn't put away the possibility of her going swimming in cold weather.

Best ResponseYou've already chosen the best response.0@Sujay But how to you justify that? Just by looking at it and logically processing it?

Best ResponseYou've already chosen the best response.1so that's the truth table for ~p > q which is the translation of "If the weather is not cold, Meg will go swimming."

Best ResponseYou've already chosen the best response.1you start off with P and Q and you fill out the first column to be T, T, F, F then you do T, F, T, F for the second column this basically sets up all the possible truth value pairings for P and Q

Best ResponseYou've already chosen the best response.1then you fill out the ~P column by flipping everything you see in the P column

Best ResponseYou've already chosen the best response.0This is probably a stupid question but how come there are 4 in each column?

jim_thompson5910

Best ResponseYou've already chosen the best response.1because there are 2^2 = 4 ways to have truth values for P and Q when they pair up

Best ResponseYou've already chosen the best response.1finally, you fill out the ~P > Q column by only writing F if ~P is true and Q is false otherwise, its true by default

Best ResponseYou've already chosen the best response.0How do we figure out if its logically equilvalent? Do I just for whichever statement makes sense in that table?

jim_thompson5910

Best ResponseYou've already chosen the best response.1make a truth table for the second statement "The weather is cold, or Meg will go swimming"

jim_thompson5910

Best ResponseYou've already chosen the best response.1and compare the truth values in the last column
