determined

Intersection definition and notation - fcorrect answer- The intersection of sets A and B
is the set of elements common to both set A and B. See note card for notation and
set builder notation

The formula for the cardinal number of the union of two finite sets - fcorrect answer- n
( A U B ) = n(A) plus n(B) - n (A intersect B )

what are disjoint sets - fcorrect answer- 2 sets that have no elements together

de morgans law (two laws) - fcorrect answer- 1. the complement of the intersection of
2 sets is the union of the complement of those sets (A intersect B)' = A' U B'
