The meaning of the question is unclear: "how many combinations CAN THEY USE..."
????
Re-post, finding a better way to pose the question.
-----------------------------------------------------------------------
Note the other tutor interpreted the question as being the number of combinations of the 4 rides they can go on, allowing the possibility that the number of rides they go on can be 0, 1, 2, 3, or all 4.
I suppose that is a possible interpretation; however, the wording to me says that the family wants to go on ALL FOUR of the rides.
