Answer:
6,720 ways
Step-by-step explanation:
Since in the problem arrangemnt is being asked this is a problem of permutation.
No . of ways of arranging r things out of n things is given by
P(n,r) = n!/(n-r)!
In the problem given we have to arrange 5 objects from set of 8 objects.
Here n = 8 and p = 5
it can be done in in
P(8,5) = 8!/(8-5)! ways
8!/(8-5)! = 8!/3! = 8*7*6*5*4*3!/3! = 8*7*6*5*4 = 6,720
Thus, number of ways to arrange 5 objects from a set of 8
different objects is P(8,5) = 8!/(8-5)! = 6,720 .
