Subset - ANSWERS-Set A is a ______ of Set B if every element in A is
also an element of B.

-Ex:

A = {5, 7, 9, 11, 13}

C = {5, 6, 7, 9, 11, 13, 14}

So, A ⊆ C but C ⊈ A



Symbol for Subset - ANSWERS-⊆,⊈



Number of Subsets - ANSWERS-There are 2 possibilities for an
element: either the element is in the subset or it's not. So the formula
is 2^n where n is the number of elements in the set.



Formula for Number of Subsets - ANSWERS-2ⁿ



Complement - ANSWERS-The set of elements from the universal set
which are NOT in the given set.

, Complement Rule - ANSWERS-P(E) = 1 - P(E') and P(E') = 1 - P(E)

sets.



Symbol for Intersection of Sets - ANSWERS-∩, and



Union of Sets - ANSWERS-The elements which are found in one or the
other of the sets.

Set - ANSWERS-A clearly defined group of objects.



Element - ANSWERS-A member of a set.
