Question

what does the word precedent mean? a decision that is good or helpful a decision that guides future decisions a decision that is not legally binding

Explanation:

In legal and general academic contexts, a precedent refers to a prior decision or ruling that is used as a standard or guide for making similar future decisions. The other options do not match this core definition: a precedent does not need to be "good or helpful" to be a precedent, and legal precedents are typically legally binding.

Answer:

a decision that guides future decisions
