[@codemathlab]

I never understood permutation and combination as good as this before.

At 30:35, since the condition is that all empty seats are next to each other, and since it is a row not a circle, then isn't it the case that there are only two configurations where all empty seats are next to each other: When the 6 people occupy seats 1-6 or 5-10. If they were to occupy seats e.g., 2-7, then wouldn't the condition be violated?

[@girishmatkar3696]

No Because the question is that all the empty seats should be next to each other

30:24= any one can explain how 7p6🤔

[@b.mohanschannelb.m.k.2901]

In the question all empty seat are next to each other... So she took those 4 empty seats next to each other... But... Now those all 4 seats are same.... But we want different arrangements (permutations)... So she took those 4 seats as one seat....(becoz seats are not varying right😅)

[@AlphaGama-s3j]

Again i have doubt , how she took 7 =n ,did you have any idea? If you know hindi then plz explain in that language that will be easy to understand this..

[@rounakdas2633]
