Thanks for the response. Yes that's how i was calculating it myself. I was actually trying to work out the percentage chance of 0.9% occuring at least once over 9 attempts. I typed in 0.991 x 0.991 nine times then subtracted the answer from 1. This seemed really time consuming so i tried to use the percentage button which i couldn't get to work. Not sure if there's an easier way of working this calculation out?
