英语翻译
A company is trying to use its printers in a more environmentally efficient way.It already has a policy that it will never print a document containing more than 10 pages.Suppose that the settings on each printer are changed from printing single sided sheets to printing double sided sheets with 2 pages per side.
Assuming that all documents of all permitted lengths are equally likely,in the long run,that fraction of the paper used will be saved under the new settings?
某公司决定要更为环保地使用打印机.该公司已规定,10页以上的文件不能打印.现假设该公司将打印机从单面打印式改成双面打印式,且每面可以打印2页.如果所有打印文件均符合打印规定,那么使用弟二种方法打印可以节约纸张吗?
