Answer:
Number of ways = 40320 ways
Explanation:
Total number of posters = 8
The points are to be arranged in the room without any definite pattern or configuration.
Since there is no definite pattern ir configuration to hang the posters, the number of ways f hanging the posters will be gotten by factorial method.
Number of ways = 8!
Number of ways= 8*7*6*5*4*3*2*1
Number of ways = 56*30*12*2
Number of ways = 1680 * 24
Number of ways = 40320
