That statement is FALSE


Sam and Mala have a conversation Sam says I am certainly not over 40 Mala says I am 38 and you are at least 5 years older than me Now Sam says you are at least 39 All statements by the two are fal?

If all statements are false, then Sam's claim of not being over 40 is false, meaning he is over 40. Mala's statement of being 38 would also be false, indicating she is not 38, so she must be either younger than 38 or older than 38. Since Sam says Mala is at least 39, and his statement is false, it means Mala is younger than 39. Therefore, both Sam is over 40 and Mala is younger than 38.


How do you construct a truth table for q arrow p?

I guess you mean q → p (as in the logic operator: q implies p).To create this truth table, you run over all truth values for q and p (that is whether each statement is True or False) and calculate the value of the operator. You can use True/False, T/F, 1/0, √/X, etc as long as you are consistent for the symbol used for True and the symbol used for False (the first 3 suggestions given are the usual ones used).For implies:if you have a true statement, then it can only imply a true statement to be truebut a negative statement can imply either a true statement or a false one to be truegiving:. q . . p . q→p--------------. 0 . . 0 . . 1 .. 0 . . 1 . . 1 .. 1 . . 0 . . 0 .. 1 . . 1 . . 1 .
