Under Rule 404(b) of they ARE, evidence of a defendant's prior similar acts or crimes, including acts that are not charged in the current case, may be admissible for purposes such as establishing motive, intent, opportunity, knowledge, identity, absence of mistake, or the existence of a common plan or scheme. This evidence helps to prove the defendant's propensity or tendency to engage in certain behaviors, which becomes relevant to evaluate their guilt or innocence in the present case. However, it's important to note that such evidence must meet certain criteria before it can be admitted. For instance, the court must determine if the evidence is indeed relevant to one of the permissible purposes provided in the instruction.
