Three married couples arrange themselves randomly in six consecutive seats in a row. find the probability that each woman will sit immediately to the left of her husband. the denominator of the probability fraction will be 6! = 720, the total number of ways to arrange six items.

1/120

The numerator of the probability fraction will be the number of ways to arrange 3 items: 3!  = 6. So the probability fraction is ...

... 6/720 = 1/120

The 3 items are the three married couples with the woman on the left.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
