In summary, finding the probability that all 7 witnesses would pick the same person means determining the likelihood of them all identifying the same person as the perpetrator or key figure in an event. This is important in legal cases and can help assess the credibility and consistency of witness testimony. To calculate this probability, the total number of possible outcomes and the number of outcomes where all 7 witnesses pick the same person must be known. Factors such as witness reliability, event nature, and biases can affect the probability. However, it should not be solely relied upon as it is based on assumptions and can be influenced by various factors.

In a homicide case, 7 different witnesses picked the same man from a lineup. The line up contained 5 men. If the identification were made by random guesses, find the probability that all 7 witnesses would pick the same person.

Hint: the last 6 witnesses each have probability 1/5 of matching 1st witness.

Btw, that means exactly 64 times out of a million attempts!

## What does it mean to find the probability that all 7 witnesses would pick the same person?

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.

## Why is finding the probability of all 7 witnesses picking the same person important?

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.

## How do you calculate the probability of all 7 witnesses picking the same person?

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.

## What factors can affect the probability of all 7 witnesses picking the same person?

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.

## Is the probability of all 7 witnesses picking the same person always a reliable measure?

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.
