Step-by-step explanation:
Section 6.1 Sets and Set Operations
Sets A set is a well-defined collection of objects. The objects in this collection are called elements of
the set. If a is an element of the set A then we write a 2 A, if a is not an element of a set A, then we
write a /2 A.
Roster and Set-Builder Notation
Roster notation will be used most commonly in this class, and consists of listing the elements of a set
in between curly braces. Set-builder notation is when a rule is used to define a definite property that
an object must have in order to be in the set.
1. Let A be the set of all letters in the English alphabet.
(a) Write A in roster notation and in set-builder notation.
(b) Is the greek letter an element of A?
Set Equality Two sets A and B are equal, written A = B, if and only if they have exactly the
same elements.
2. Let A = {a, e, l, t, r}. Which of the following sets are equal to A? (Choose a
