In a hybrid set, if the cardinality of set A is 5 and set B is 3, what can be inferred about the hybrid set formed by their union?

In a hybrid set, if the cardinality of set A is 5 and set B is 3, what can be inferred about the hybrid set formed by their union?

Step 1: Understand what cardinality means. Cardinality is the number of elements in a set.
Step 2: Identify the cardinality of set A, which is 5.
Step 3: Identify the cardinality of set B, which is 3.
Step 4: Determine the maximum cardinality between the two sets. The maximum is 5 (from set A).
Step 5: Consider that when you combine (union) two sets, the total number of unique elements could be equal to the maximum cardinality or more if there are common elements.
Step 6: Conclude that the cardinality of the hybrid set (union of set A and set B) will be at least 5, but could be higher if there are elements that are in both sets.
