A library subscribes to two different weekly news magazines, each of which is supposed to arrive in Wednesday's mail. In actuality, each one may arrive on Wednesday, Thursday, Friday, or Saturday. Suppose the two arrive independently of one another, and for each one P(Wed.) = 0.28, P(Thurs.) = 0.38, P(Fri.) = 0.21, and P(Sat.) = 0.13. Let Y = the number of days beyond Wednesday that it takes for both magazines to arrive (so possible Y values are 0, 1, 2, or 3). Compute the pmf of Y. [Hint: There are 16 possible outcomes; Y(W,W) = 0, Y(F,Th) = 2, and so on.] (Enter your answers to four decimal places.)

4. Builtrite D is considering the purchase of a new machine for $500,000 which would require a $5000 installation charge. Employees would need to go through a brief training session to operate the machine properly which would cost $25,000. In addition, an increase in net working capital of $30,000 would be required. The machine has an expected life of 10 years and due to efficiencies, labor costs are expected to decrease $150,000 annually (before depreciation and taxes). Assume straight-line depreciation, a 34% marginal tax rate and a cost of capital of 15%. Should Builtrite D purchase the machine?
