Final answer:
A valid inductive argument is one that starts with specific observations and leads to a probable conclusion. It is rooted in observations and experiences that support a probable generalization, but unlike deductive arguments, it doesn't guarantee the truth of its conclusions.
Step-by-step explanation:
The best description of a valid inductive argument is 1) An argument that is based on specific observations and leads to a probable conclusion. Inductive reasoning uses observations or experiences to draw general conclusions about the world. The strength of inductive inferences depends upon the reliability of evidence and their relation to the conclusions. A strong inductive inference is one where, if the evidence offered is true, then the conclusion is probably true. Unlike deductive reasoning, which guarantees the truth of the conclusion if the premises are true, inductive reasoning does not provide this guarantee, but it can offer a high probability of the conclusion being true when based on strong, relevant evidence.
