Question 606633: Given the sets:
vowels = {'a' ,'e', 'i', 'o', 'u'} and name = {'a', 'l', 'l, 'a', 'n'}
Which is FALSE?
- name ∪ vowels = {'a'}
- 'a' ∈ (vowels ∩ name)
- The cardinality of name = The cardinality of {'a', 'l', 'n' }
- The cardinality of vowels is equal to the cardinality of name
I would normally say it would be D in this case, as I think duplicate letters don't count such as name would be 3 and vowels would be 4.

Choice A is false. So there must be a typo if there is only one possible answer. My guess is that the union symbol in choice A should be an intersection symbol.

If that's the case, then the answer is choice D.
