The number of ways the guests could arrange themselves on a four-person couch can be calculated using the permutation formula.
P(n, r) = n! / (n-r)!
In this case, n = 33 (number of guests) and r = 4 (number of seats on the couch).
P(33, 4) = 33! / (33-4)!
P(33, 4) = 33! / 29!
P(33, 4) = 863,880
Therefore, there are 863,880 ways in which the 33 guests could arrange themselves on the four-person couch.
