There are 6 persons including bride and groom. right.

we have to arrange them in a row.

Now you can think , in whatever manner you place them , either the bride would be to the right side of the groom or the left side. Is there other possibility ? No.

so ultimately

way to arrange the bride to the left of groom(WL) + way to arrange bride to the right of groom(WR) = total possible ways to arrange 6 people in a row.

Now you can think that WL and WR are symmetric ,i mean WL=WR

and total number of ways to arrange 6 people in a row = 6!

so ultimately WL= 6! / 2 =>360

6 people including the bride and the groom can be arranged in 6! possible ways out of which bride is left to the groom in half of the total possible ways and to the right of the groom in the other half of the total possible ways.

So the answer is 6!/2
