For your birthday, your parents take you to dinner and offer to let you have any 2 desserts on the menu. The restaurant, famous for its desserts, lists 10 on its menu. How many different combinations of 2 desserts can you order?
there would be like 20 bc u multiply 2 * 10 and u get 20. but u also have one with all the others. like for instance u have a particular flavor (in this case ima say blueberry pie) u would have blueberry pie with 9 other ones. then yea. i hope this helps :)
