Question

Determine whether the following arguments are valid, invalid, strong, or weak (to do this, you'll first have to determine if the arguments are best interpreted as deductive or inductive).

2. "Some dogs are mammals. All mammals are animals. Therefore, all dogs are animals."

3. "People who don't wear bike helmets have a 5% chance of getting in a horrible wreck each year. Sarah does not wear a bike helmet. Sarah will get in a horrible wreck this year."

7. "Some people like to jog. Everyone who likes to jog loves the color pink. Thus, some people love the color pink."

Answer 1

2. The premises "Some dogs are mammals. All mammals are animals" do not draw good inferences, and also, the conclusion that is drawn from the premises are invalid. Hence, this argument is a Deductive Invalid Argument.

3. This is a deductive argument, as the form is from general to specific. Premises are true, as the inference is true, but the conclusion is false. Hence, this argument is a Deductive Invalid Argument.

4. This is a deductive argument as it follows the general to specific form. The inferences drawn in the premises are true and is followed by a valid conclusion. Hence, this is Deductive Valid Argument.
