Answer:
Step-by-step explanation:
Permutation had to do with arrangement.
Arranging r people out of the pool of n people can be done in nPr number of ways
nPr = n!/(n-r)!
From the question, we want to know how many seating arrangements are possible if 4 people out of a group of 14 want to sit on the park bench, the can be done in 14P3 number of Ways
14P3 = 14!/(14-3)!
14P3 = 14!/11!
14P3 = 14×13×12×11!/11!
14P3 = 14×13×12
14P3 = 2184 ways
This means that they can be arranged in 2184 number of ways
