It is calculated as 5! i.e.,
5*4*3*2*1 = 120
So probability is 20 here

Probabilities for:

- One possibility (e.g. blue shirt) = 1/5 (20%)
- One possiblity or another (e.g. blue or white shirt) = 1/5 + 1/5 = 2/5 (40%)
...
- One possibility and another in a second turn (e.g. first search gives blue shirt, second search gives white shirt) = 1/5 * 1/5 = 1/25 (4%)
- Two possibilities and another two in a second turn (e.g. first search gives blue or white shirt, second search gives blue or green shirt) = 2/5 * 2/5 = 4/25 (16%)
...

Got it..?
