The probability that a device passes the quality control test is $0.8$. Find the probability that a given device will pass the test on the third try.
I don't understand how to go about answering this question. It seems to me like there isn't enough information. Do I assume each trial is independent? If so, I thought to use the probability distribution of a geometric RV, but this PMF gives the probability of obtaining the first success at the kth Bernoulli trial. The question says nothing about it having to be the first success. So is the answer just $0.8$ since the probability is the same for any trial?
