# Letters Chatters Extension

Check Letters Chatters.

Taking a general Case,

In a town with a population of $n$, a person sends 2 letters to 2 random distinct people in the town, each of whom repeats the procedure. Thus, for each letter received, two letters are sent to 2 random distinct people (could even be to the person who sent the letter).

It is Assumed that all the letters reach their respective destination.

Just If the probability Of Letter to reach their respective Destination is $\dfrac{1}{2}$.

Then What Is the probability that in the first $m$ stages, the person who started the chain letter will not receive a letter .

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Yes, I did see this. And i did think about it. But after a while it overwhelmed me. May not be possible to solve this by hand. Will try to do it again sometime.
