The secretary in exercises 2.121 and 3.16 was given n computer passwords and tries the passwords at random. exactly one of the passwords permits access to a computer file. suppose now that the secretary selects a password, tries it, and—if it does not work—puts it back in with the other passwords before randomly selecting the next password to try (not a very clever what is the probability that the correct password is found on the sixth try?

There is a probability that the correct password is found on the sixth try.

Step-by-step explanation:

We have n passwords, only 1 is correct.

So,

Since a password is put back with other, at each try, we have that:

The probability that a password is correct is

The probability that a password is incorrect is .

There are 6 tries.

We want the first five to be wrong. So each one of the first five tries has a probability of . So, for the first five tries, the probability of getting the desired outcome is .

We want to get it right at the sixth try. The probability of sixth try being correct is .

So, the probability that the first five tries are wrong AND the sixth is correct is:

There is a probability that the correct password is found on the sixth try.

2 5/8 is the final answer! : )

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes.
