An Olympic archer misses the bull's-eye 11% of the time. Assume each shot is independent of the others. If she shoots 9 arrows, what is the probability of each of the results described in parts a through f below?
a) Her first miss comes on the eighth arrow.
The probability is
. 0487
(Round to four decimal places as needed.)
b) She misses the bull's-eye at least once.
The probability is
. 6496
(Round to four decimal places as needed.)
c) Her first miss comes on the second or third arrow.
The probability is
. 1850
(Round to four decimal places as needed.)
d) She misses the bull's-eye exactly 3 times.
The probability is
