D
234

Answer 2

is it d or am i wrong?

Answer 3

Confusing question... how are we supposed to interpret these sets? Are we supposed to find the intersection of those sets, or the cardinality of the intersection?

Answer 4

i have no idea? that is what the question says.. word for word :/

Answer 5

I would have a tendency to answer the question this way:
Set E = {134,304,234,39}
Set W = {232,232,234,205}
\[E \cap W = \text{{234}}\]
Cardinality is simply the number of elements in the set, so 1.
