1. A new employee is supposed to be sorting coated lenses into one of three bins: ship, rework, or scrap. However, this employee was not well trained and sorts 50 lenses by randomly putting each lens in one of the three bins.

(c) Find E(Y ).
(d) Find Var(Y).
2. The new employee from the previous problem was retrained and put back to work sorting lenses into three bins: ship, rework, and scrap. A well-trained worker will sort with 98% accuracy.
