1. Find m_X for the following discrete probability distribution:

\fThe following information is for questions 4 - 6: Jenny is a 60% free-throw shooter. She gets to shoot a second free throw if and only if she makes her first shot. She can score 0 points (if she misses her first shot), 1 point (she makes her first but misses her second), or 2 points (she makes both shots).The following information is for questions 7 and B: In a certain mid-size city, 90% of the high school graduates are from public schools and the other 10% are from private schools. Of the private school grads, 80% go on to complete college, but only 50% of the public school grads complete college. 13.
