// I am NOT sure about this, but I think it's part to part.
If it was part to whole ratio it will be out of total number of videos.
like ratio of videos that are drama to total videos.....
or ratio of videos that are not drama to total videos.....
You are talking part of each ratio and combining to a different one, so I think it's part to part.
//Again I am not sure about this. But kinda make sense.
