The actual ans is 6×5×4×3 To write the ans in factorial form they had been writing 6!÷2!

Are these questions provided beforehand or we got to see them directly on these videos

Does anyone know why did we divide it by 2!?

[@SimpleSage19]

Because the order doesn't matter, if we do not divide by 2! then it will be considered permutation but we're supposed to use combination. In simple words 1,2,3,4 this order is considered same as 2,3,4,1 but if we don't divide by 2 it will be counted as 2 separate events.

@@SimpleSage19 thank you for taking the time to reply

[@Vishal00567]

he divided by 2! to make it in factorial form.

[@bhagyeshbhardwaj]

@@SimpleSage19 wrong he divided by 2! because there are only 4 dice and the last dice has 3 possible outcomes but after that no other dice is there so to make 6! into 6*5*4*3 he did 6!/2!

Just to write this in factorial form
