1. Find the following cardinalities (Do not list the elements of the sets). Show your work. (a) ([10]{1,3, 4, 5} x {2, 5, 6, 7}) {4, 5, 6, 7} {2,7,8,9}|. 100 16 (164) = 72. (b) (([10] - [6]) - {6, 7, 8, 9, 10}) {1, 2, 3, 8, 9, 10}|. In the following picture the the shaded regions correspond to the sets that are subtracted. Therefore, the cardinality of the set that remains is 22.
