This means that you are trying to determine the likelihood that all 7 witnesses, who were present during a specific event, would identify the same person as the perpetrator or key figure in the event.
This can be important in legal cases or other situations where witness testimony is crucial. It can help determine the credibility and consistency of the witnesses' statements.
To calculate this probability, you would need to know the total number of possible outcomes (or people) that the witnesses could choose from, as well as the number of outcomes that would result in all 7 witnesses picking the same person. You would then divide the number of favorable outcomes by the total number of possible outcomes.
The probability can be affected by various factors such as the reliability of the witnesses, the nature of the event, and any potential biases or external influences.
No, the probability is not always a reliable measure as it is based on assumptions and can be affected by various factors. It should be used as a guide and not the sole determining factor in a case or situation.
