The total number of ways in which #7# people can be seated in a row of #7# seats is: #7 * 6 * 5 * 4 * 3 * 2 * 1 = 7! = 5040# to find the number of these ways that are unacceptable because they result in the particular pair being sat next to one another, we can think of seating #6# people in a row of #6# seats, excluding one person from the particular pair, then suppose they arrive and squeeze.
