I wasn't sure if you needed help with #3 too so I will do it for yo just in case.
3. because it is a combination order doesn't really matter and it doesn't say that a shirt or short cannot be repeated this mean that for each pair of shorts you have 5 tops to choose from. so just take 3*5=15 and that is how many different matches can be made!
