Just wondering if anyone can point me in the right direction as to how to solve this?....
"In an experiment at Boston's Computer Museum, each of 10 judges communicated with four computers and four other people and was asked to distinguish between them.
1. Assume that the first judge cannot distinguish between the four computers and the four people. If this judge makes random guesses, what is the probability of correctly identifying the four computers and the four people?
2. Assume that all ten judges cannot distinguish between computer and people, so they make random guesses. Based of the previous result, what is the probability that all 10 judges make all correct guesses?
Assumption (1): The judge knows in advance that there are four computers and four people, therefore the judge (being logical) will always guess four computers and four people.
Assumption (2): The judge does not know how many of each there are, so potentially the judge could guess that they are all computers, or that there are two computers and six people, etc.
Obviously in (2) the probability of guessing correctly is reduced.
You can pick which assumption to work with and we can work from there.
When you have ten judges, they all have the same probability of guessing correctly, so..
