I need your help with another problem... I would really appreciate it.
During a circumstancial process, n evidences with probatory value of 2% each are considered.
1) evaluate the probability P1 of guilty on the base of n=1 evidence
2) evaluate P10 of guiltyness on the base of n=10 evidences
3) calculate the minimal number N of evidences such that the probability of guiltyness exceeds 90%.
sorry for my bad English too...
Thanks a lot.
