# Probability to find the treasure five times in row

Let's pretend there are 10 doors in front of me. Behind one of them, there is a treasure and nothing behind all the others. Intuitively, I can easily determine I have 1 chance out of 10 the pick open the right door (the one with the treasure). I repeat this 5 times (i.e. all door closed, open one door). What are my chance to find the treasure the five times?

In brief, I am wondering how to determine the probably that I find the threasure 5 times in row.

 As @Edward pointed out, please add some details. – mbq♦ Sep 13 '10 at 12:40

Is the location of the treasure changed after each attempt? Wouldn't it be $(10\%)^5$?
