Ok so 5 people place their names in a hat, what is the probability that they will each pull out there own name?
So correct me if i'm wrong (chances are I am) but
there are 5! = 120 permutations, with only 1/120 chance of them chosing their own names

Hello, TommyBoy22!
You are absolutely correct!Ok, so 5 people place their names in a hat.
What is the probability that they will each pull out there own name?
So correct me if i'm wrong (chances are I am) but ...
There are permutations, with only chance of them chosing their own names.
Another approach:
The first has a chance of getting his name.
The second has a chance of getting his name.
The third has a chance of getting his name.
. . . and so on.
