An archer hits a bull's-eye with a probability of 0.09, and the results of different attempts can be taken to be independent of each other. If the archer shoots nine arrows, calculate the probability that: (a) Exactly two arrows score bull’s-eyes. (b) At least two arrows score bull's-eyes. (c) What is the expected number of bull's-eyes scored?
