    1:17:31 Sir proud to say I hsve got a more elegant solution😌
    We cant take both members of any couple so it is must to take 1 member from each of the 4 couples to form a committee of 4.
    So we have to select 1 out of 2, 4 times
    So we can simply say answer will be 2×2×2×2=16

    Sir, I have a doubt. In the second problem of derangement near about 2:52:00 why can't we use this approach.
    The approach is first we put C1 to E2 this will be the only way, then we derange C3,C4,C5,C6 toE3,E4,E5,E6 Then we will to arrange C3,C4,C5,C6 to E1, and at last we will arrange C2 to E1,E3,E4,E5,E6.
    Is there any arrangement which is not noticed or not given by this approach.

    • @Khushi-ky5kl
      @Khushi-ky5kl Год назад

      We can't do it in this way because in question we are said what there should be no couple if we take the case of only couple than that case will be not be removed from total in which there were 1 couple in the comity so answer will come wrong
