Let's analyze each argument to determine whether it is an example of
inductive reasoning or
deductive reasoning.
---
Definitions:
-
Inductive Reasoning: Drawing a general conclusion based on specific observations. The conclusion is *probable*, but not guaranteed.
-
Deductive Reasoning: Drawing a specific conclusion from general premises. If the premises are true and the logic is valid, the conclusion *must* be true.

1.
> 1 is an odd number.
> 11 is an odd number.
> 21 is an odd number.
> Therefore, all numbers ending with 1 are odd numbers.
- This starts with
specific examples (1, 11, 21) and draws a
general conclusion about all numbers ending in 1.
- It’s
not logically certain (e.g., what about 101? But we’re assuming the pattern holds).
- This is
inductive reasoning.

2.
> Dogs don’t eat banana.
> Sam is a dog.
> Therefore, Sam does not eat banana.
- Starts with a
general rule ("Dogs don’t eat banana") and applies it to a
specific case (Sam).
- This follows a
logical form: All A are B. C is A. Therefore, C is B.
- This is
deductive reasoning.

3.
> Andre did not win the game 2 days ago.
> Andre did not win the game yesterday.
> Therefore, Andre will win the game today.
- Based on
past observations, it predicts a
future outcome.
- The conclusion is
not logically necessary — just a guess based on pattern.
- This is
inductive reasoning, even though it’s flawed (assuming a trend will reverse).

4.
> Hans has not bought any snack.
> His parents have not bought any snack.
> Therefore, there won’t be anything to eat for the picnic.
- This assumes that
only Hans and his parents could have bought snacks.
- It’s a
specific conclusion drawn from
specific facts, but it depends on an
implicit assumption (no one else bought food).
- While it seems logical, it’s
not necessarily valid unless we know no one else contributed.
- However, it attempts to apply
specific facts to reach a
conclusion about a situation.
- This is more
inductive because it generalizes from partial information (no one mentioned buying snacks) to a total lack of food.
- But note: if we assume only these people were responsible, it could be deductive. But since that isn't stated, it’s
inductive.

5.
> All birds have feathers.
> Chickens are birds.
> Therefore, chickens have feathers.
- General premise → Specific instance → Logical conclusion.
- Classic
syllogism.
- If the premises are true, the conclusion
must be true.
- This is
deductive reasoning.
