The two given sets have a common element "11ebb17b_29f1_fad7_afdc_67f9a70d281c_TB8591_11" which is a positive integer. Thus, the sets are not disjoint. Two sets are disjoint if they have no elements in common. In this case, the two sets have the same first four digits before the underscore, which means they have common elements. Therefore, the sets are not disjoint.
