1 answer:
Answer:
If there are 5 persons and at a time only 3 can be arranged, the total number of arrangements is 60
Option C is correct
Step-by-step explanation:
There are 5 persons and at a time only 3 can be arranged.
The total number of arrangements = nPr = n!/(n-r)!
Here n = 5 and r = 3
nPr = n!/(n-r)!
nPr = 5!(5-3)!
nPr = 5!/2!
nPr = 5*4*3*2!/2!
nPr = 5*4*3
nPr = 60
So, if there are 5 persons and at a time only 3 can be arranged, the total number of arrangements is 60
Option C is correct.
