Please show me the detailed solution.

A manufacturer of electronic calculators offers a oneyear warranty. If a calculator fails for any reason during this period it is replaced. The manufacturer offers at most one replacement per purchase. The cost of manufacturing a calculator is $50 and the prot per calculator is $25. The time to failure is well modeled by the following probability distribution: f(93) = 0.1 8012, 3: \":> 0 where r is the time to failure in years. What fraction of the calculators is likely to fail within the warranty period? 1What is the expected net prot per calculator correcting for the warranty related expenditures
