It's simple. First, edit the page or category that you wish to remove a category from. Then, on the right hand side, you will see a "Categories" section, displaying a list of all the categories on that page. If you hover over the category you want to remove, a small trash can (rubbish bin) will appear, click it and it will remove the category. You will then need to save the page.
