13-89.

Sure Shot Jane can hit the bull's eye with a bow and arrow

To get the probability, add together the probabilities of three arrows, four arrows, and five arrows hitting the bull's eye.

The probability of getting three hits (and two misses) is:

_{\large{_{5}C_{3} \left(0.9\right)^{3}\left(0.1\right)^{2}}}

Use the same method to find the probabilities of getting four hits and five hits.
