If 5 people randomly get seated in consecutive seats in a theatre, what is the probability a particular person A sits in the first seat? What is the probability that the first two seats are occupied by A, B in the same order? In some order? What is the probability that A and B sit next to each other?
Homework Answers
a) probability a particular person A sits in the first seat =1/5
b) probability that the first two seats are occupied by A, B in the same order =(1/5)*(1/4) =1/20
c) probability that A and B sit next to each other =P(considering A and B as one unit and can interchange position within)
=2*4!/(5!)=2/5

a.) Suppose that n people are seated in a random manner in a row of n theater seats. What is the probability that two particular people A and B will be seated next to each other? The answer to the question is 2/n, but I'm not sure how to do the process. My teacher said that it was the # of favorable outcomes/ total number of outcomes, which was 2* (n-1)! / n!, which simplifies to 2/n. Is this process...

In how many ways can three couples be seated in a row so that each couple sits together (namely next to each other) in a circle ? Hint : As in the general comment, recall that rotations matter. It may be useful to imagine a round table with 6 chairs, and a single mark on the table, between two specific chairs. Observe that for some configurations of the 6 people, the mark is between two different couples, denoting the mark...

6) At a restaurant, fifteen couples are seated at a large round table with thirty seats. Before the couples arrive, the waiter puts a card on each plate with the name of one person on it. Assume that the cards are placed randomly (with no attention to a person's gender or which person is a partner of which other person); that is, al rearrangements of the name cards are equally likely. What is the expected value of the number of...
