Week 2 Question 1

Chris has 15 dollars. A new shirt costs 12 dollars. Chris comes back with a new shirt so Chris must have 3 dollars left.

This a scenario I just made up and now lets test to see if it makes any sense.

The premise is plausible

Chris could very well have 15 dollars in cash and a new shirt can cost 12 dollars.

The premise is more plausible then the conclusion

Chris having money and looking to buy a new shirt is more plausible than him having spent the money on a new shirt.

The argument is weak for many reasons. A who knows if chris bought that 12 dollar shirt as opposed to a 10 dollar shirt. Also who knows if Chris even bought the shirt to begin with.

The argument isn't valid either because the premise and the conclusion might have nothing to do with each other.
