It is known that a certain lacrosse goalie will successfully make a save 87.58% of the time. Suppose that the lacrosse goalie attempts to make 12 saves. What is the probability that the lacrosse goalie will make at least 10 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 =
