    Posting just the one question instead of your whole assignment is an improvement, but you're still supposed to show that you've made some effort yourself. See: https://www.physicsforums.com/showthread.php?t=531087

    First you need to find the total number of combinations having three available spaces out of ten. (the easy part).

    Then you need to find all the combinations of ways that you can have two adjacent spaces when there are three (of 10) spaces available.
