Discussion Overview

The discussion revolves around calculating the probability that two individuals, Ram and Shola, will choose the same subset of items from a larger collection. Specifically, both are selecting 16,384 items from a total of 65,536 items. The focus is on the combinatorial aspects of this selection process.

Discussion Character

  • Mathematical reasoning

Main Points Raised

  • One participant presents the problem of finding the probability that Ram's and Shola's selections of 16,384 items from 65,536 items are identical.
  • Another participant asks for the number of ways to choose 16,384 items from 65,536 items, indicating a need for combinatorial calculations.
  • There is a reiteration of the random nature of both Ram's and Shola's selections, emphasizing that both are making their choices independently.
  • A further inquiry is made about the total number of ways to pick the same subset, suggesting a focus on the combinatorial outcomes of their selections.

Areas of Agreement / Disagreement

Participants appear to agree on the random nature of the selections but have not yet reached a consensus on the specific calculations or methods to determine the probability.

Contextual Notes

The discussion lacks detailed calculations or assumptions regarding the combinatorial formulas that would be necessary to derive the probability. There are no explicit definitions provided for terms like "same subset" or the method of selection.

Who May Find This Useful

This discussion may be useful for individuals interested in combinatorial probability, particularly in contexts involving large sets and random selections.

There is a collection of 65536 different items. Out of these items ,
Ram chooses 16384 items.Shola also wants to choose 16384 items out of
this collection of 65536 different items. Find the probability that
the collection of items which Ram has choosen will be same as the
collection of items which Shola will choose.

Hello and welcome to MHB, Diganta28! :D

Can you compute how many ways there are to choose 16384 items from 65536 items?

Ram randomly picks and Shola also picks randomly

Yes, but how many ways are there to randomly pick 16384 items from a set of 65536 items, and how many ways can they both pick the same subset?
