Question

Five letters are sent to different persons and addresses on the five envelopes are
written at random. The probability that all the letters reach correct destiny is​

Answer 1

probability that all the letters reach to correct destiny = $\frac{1}{120}$

Step-by-step explanation:

Number of letters = 5

Number of envelopes written different name and addresses = 5

first letter has five possible arrangements, second letter has four possible arrangements and so on...

The number of ways to arrange the letters = 5!

                                                                       = 120

Only one arrangement will give each letters to correct destiny.

Therefore, the probability that all the letters reach to correct destiny = $\frac{1}{120}$

Option d. is the answer.
