title: How to calculate a probability of events in excel?
body: <p>Could someone help me with an excel formula to run a test 1000 times where there are only two possibilities of the event to occur out of 40 outcomes. Is it possible in excel?</p>
  
  <p>For example: I have 40 numbered stones in a bunch from 1 to 40. How many times I randomly pick stone no.1 or 2 when I try this 1000 times?</p>
  
  <p>Is it possible to execute this in excel and get a detailed answer in %?</p>
