If there are 4 rows of seats for 20 students, then each row must have 5 seats.20 students can fill 5 seats in (20 x 19 x 18 x 17 x 16) = 1,860,480 different ways.
students can be seated in 16 diffrent ways. multiply or draw a table. * * * * * Unfortunately, that is an incorrect answer. The correct answer is 4*3*2*1 = 24 ways. For the first seat, on the left, you can pick any one of the 4 students. For the next seat, you have only three students so you have 3 choices. So the number of ways of filling the first two seats is 4*3. Continue the process.

-- The first place can be any one of 20 students. For each of these, -- the second place can be any one of the remaining 19 students. For each of these, -- the third place can be any one of the remaining 18 students. For each of these, -- the fourth place can be any one of the remaining 17 students. So the four places can be assigned in any one of (20 x 19 x 18 x 17) = 116,280 ways.
