Involving the expected number of hits for a baseball player during a certain month. Assume that the batter hits with probability 0.25 against left-handed pitchers, and with probability 0.15 against right-handed pitchers. Both situations are Bernoulli processes. One month the player bats 20 times against left-handed pitchers and 65 times against right-handed pitchers.

How many hits should the batter expect to get during this month?
