You decide that by considering all of the evidence and deciding what evidence is more believable. This is a lower standard than proof beyond a reasonable doubt.

If you find that [this offense has] [these offenses have] not been proved, you must disregard [it] [them].2 If you find that [this offense has] [these offenses have] been proved, you may consider [it] [them] to help you decide any matter to which [it is] [they are] relevant. You should give [it] [them] the weight and value you believe [it is] [they are] entitled to receive. You may consider the evidence of such other act[s] of [sexual assault] [child molestation] for its tendency, if any, to show the defendant's propensity3 to engage in [sexual assault] [child molestation] [.] [, as well as its tendency, if any, to [determine whether the defendant committed the acts charged in the Indictment] [determine the defendant's intent] [determine the identity of the person who committed the act[s] charged in the Indictment] [determine the defendant's (motive) (plan) (design) (opportunity) to commit the act[s] charged in the Indictment] [determine the defendant's knowledge] [rebut the contention of the defendant that [his] [her] participation in the offense[s] charged in the Indictment was the result of (accident) (mistake) (entrapment)] [rebut the issue of __________ raised by the defense].]

Remember, the defendant is on trial only for the crime[s] charged. You may not convict a person simply because you believe [he] [she] may have committed similar acts in the past.
