    probability that the first seven tries are misses: (0.8)^7 probability that the eighth one hits: 0.2 probability that the first seven tries are misses and the 8th one is a hit: P = (0.8)^7*(0.2)

    Oh! Okay, i get it now. There is an 80% chance that he misses. That's where you got the 0.8 from. I understand now.
