A small market orders copies of a certain magazine for its magazine rack each week. Let X=X= demand for the magazine, with pmf   x p(x) 1 1/15 2 2/15 3 3/15 4 4/15 5 3/15 6 2/15   Suppose the store owner actually pays $ 1.25 for each copy of the magazine and the price to customers is $ 3.75. If magazines left at the end of the week have no salvage value, calculate the expected profit.
