Hi P.S.,
As a follow up post to my question about my inferences. I tried to "hurdle the uncertainty" as your lesson book explains by thinking about the numbers in this game (especially since it's an UNDEFINED game). I realized that the game only provide a minimum of 1 variable but realized the rules lead to more than just 1 variable.
I came up with these inferences that throughout the game weren't as helpful as the chain inferences (from my previous post). Can someone correct if the following inferences are correct or incorrect?
From rule 1 because of the conditional statement & it's contrapositive that from positive negative as:
Positive rule: M L OR S
Negative contrapositive: NOT L and NOT S NOT M
I inferred that at most 2 of the variables can go (either M with L or M with S- but not both- like the rule states). Meaning that 1 of them must be out.
Does this affect the minimum # of variables that can go in?
I wrote: 7 (total # of variables) - 1 (either M with L or S) = 6 variables. A minimum of 6 variables can go in (1 of L or S must be out).
From rule 4 because of the conditional statement & it's contrapositive that from positive negative as:
Positive rule: G H AND Z
Negative contrapositive: NOT Z OR NOT H NOT G
I inferred that at most 1 of the variables can go .
Does this affect the minimum # of variables that can go in?
7 (total # of variables) - 3 (contrapositive states that all 3 could be out) = 4 variables. A minimum of 4 variables can go in (these 3 could be out).
As I mentioned, these inferences weren't as helpful in the questions as I thought it would be. Instead my inference were more helpful. But I wanted to know if these inferences are worth or correct to make (before starting the questions).
Thanks in advance! Appreciate your time and help
