Question #18471

if there are 10 balls in a box (9 black and 1 white) what is the probability of pulling out a black ball 6 times in a row? Each time all balls are replaced so there is always 10 balls (9 black and 1 white). Basically I'm asking what is the probability of a 90% chance event happening six times in a row?
