<PRE><B>Question 838518</B>
An olympic archer is able to hit a bullseye 80% of the time. assume each shot is independent of the others. if she shoots 10 arrows,
a. what is the probability that she never misses:: 0.8^10 = 0.1074
----------------------------------------------
b. what is the probability that she gets exactly 8 bulleyes.
P(x = 8) = 10C8(0.8^8)(0.2^2) = binompdf(10,0.8,8) = 0.3020
----------------------------------------------
c. what is the probabilty that she hits the bullseye more than she misses?
P(6&lt;= x &lt;=10) = 1 - binomcdf(10,0.8,5) = 0.9672
-----------------------
