8. (2 points) It is known that a certain lacrosse goalie will successfully make a save 89.55% of the time. Suppose that the lacrosse goalie attempts to make 13 saves. What is the probabil- ity that the lacrosse goalie will make at least 11 saves?
Let X be the random variable which denotes the number of saves that are made by the lacrosse goalie. Find the expected value and standard deviation of the random variable.
E(X) = σ =
