You have been selected to be part of a police line-up for a crime committed by three perpetrators on one victim. In this line-up, only one person will walkout to be seen at a time and will then move on. A witness to the crime will identify the person as one of the three perpetrators or not one of the three and then move on to the next person in the lineup. This is not a very reliable witness. The witness will identify anyone as a perpetrator at random with probability of 0.4. If you are the 9\"\" person in line, what is the probability that 3 perpetrators have been identified before your turn
