7 thoughts on “Identical objects, distinct groups

  1. Sir,

    Firstly, thank you for this blog ! It is of immense help to Non-math background students.

    For the Q5.if the fish were all distinct then the number of combinations would have been 5^12, right? (Sending n distinct objects to r distinct places).

    Please correct me if wrong.


  2. Hi J,
    I have a doubt, I recently came across this question in a mock exam, A young princess was walking in a garden full of flowers of five different varieties – Jasmine’s, Tulips, Daffodils, Lilies and Roses. In how many ways can she pick 12 flowers for her grandmother?

    I tried to use the FPC and ended up with 5 to the power 12 and the answer, was wrong and it used the partitions logic in the solution, could explain why?
