There are 6 performers who will present their comedy acts this weekend at a comedy cloub. One of the performers insists on being the laast stand-up comic of the evening. If this performer\'s is granted, how many different ways are there to schedule the appearances?

[ ] ways

Solution

If one of the performers , insists on being the laast stand-up comic of the evening

so there are only 5 performers whose order can be varied.

So, 1st position --- 5 ways

2nd position ---- 4 ways

3 rd position ---- 3

4rth position ---- 2

5th position ----- 1 way

So, all together 5*4*3*2*1 = 120 ways to schedule the appearances
