Induction v/s Deduction

Induce and Deduce

Induce : a form of reasoning under which a conclusion is drawn on the basis of a large number of positive examples. For example, after seeing a large number of cows, we conclude a cow has four legs, white colour, two horns symmetrically placed on the head etc. Inductive reasoning, though usually leads to correct conclusions, yet the conclusions may not be irrefutable.

Deduce/Infer : to derive as a conclusion from something known or assumed. It is an irrefutable form of reasoning. By irrefutable form of reasoning we mean that the conclusion arrived at through deductive (i.e., any irrefutable) reasoning process is always correct, if the hypotheses (or given facts) are correct. This is the form of reasoning which is dominantly applied in Mathematics.
