You are planning to purchase a new computer with spreadsheet word processing software and an internet browser. there are three hardware platforms to choose from:
a macintosh compatible platform
an IBM compatible platform
and a UNIX platform.
You are unsure whether to use Lotus or Excel as your spreadsheet software and whether to install Netscape or Internet Explorer as your internet browser. As for word processing, the Macintosh platform includes a free copy of Macwrite Pro, so you dont need one, while you must choose between Word Perfect and Microsoft Word in the event that you choose one of the other 2 platforms.
Given these choices, how many possible computer configurations are possible?
