I need help with the question below

0520Midt... x T 8 / 10 + 66.7% 8. (25 points) For this question, let U denote the set of all finite subsets of N with cardi- nality 2 or more that do not include 1 as an element. So, for example: . {2,6, 7) EU . {2. -3, 4) @ U (because -3 is not a natural number) . {1, 2,3} # U (because we don't allow 1) . {7) # U (because the set needs at least 2 elements) . (2rrc N)
