    Sir in the questions where we have to pick balls without replacement from a bag of 20 balls we have to find the minimum number so rather than doing 8+7+1=16
    Can't we do 7+5+1=13
    As in the question they have not mentioned the sequence so this will be the smallest number.

    • @Vinnie1995

      Same thinking

    • @NotEvenone-j3s
      @NotEvenone-j3s 6 месяцев назад +1

      13 is right answer

    • @mohinijain1088
      @mohinijain1088 4 месяца назад

      Bcz if we pick 13 balls then we can't be assured that we have picked atleast one ball of each colour. But if we pick 16 then we are assured of it.

    I want to know that this is the also right way or not ?
