Answer 1

Hey there! so the point is to try and figure out how many combinations of 2 letters exist. one way to accomplish this is to make a list. I would start with h. So your list for h would be (h,h) (h,o) (h,p) (h,e) then move on to your next letter. hope this helps!

Answer 2

The answer to B is: HP, HE, H and O, HH, OO, EE, PP, PE, PO, and EO
