MCQ's in Mathematics
Good idea to begin a page to collect examples of mc questions. I revised the page a bit, to add an introduction to the page, and to simplify the heading structure. When a page has a meaningful page name, I'm more inclined to begin the page with text, rather than a heading which says nearly the same thing as the page name. Hope it's OK that I went ahead with editing the page. Take a look and see what you think. As this is a wiki, we should feel free to edit works, as we see the need, which are in the main space of the wiki (user pages/subpages are viewed as belonging specifically to the user, so we refrain from editing these, except for comments and certifications and the like).
Also, note that I created a category for probability, so I put that page in the new category, which is a subcategory of mathematics.
The link on the page seems correct. Are there other links that you have a question about? How do you want to use subpages?
