Equal and Equivalent Sets

Roberto Layague Jr.

Multiple Choice

What is the cardinality of the set?

A = {0, 1, 2, 3}

• n(A) = 4

• n(A) = 3

• n(A) = infinity

• n(A) = 0

Multiple Choice

What is the cardinality of the set?

B = {3, 2, 1, 0}

• n(B) = 4

• n(B) = 3

• n(B) = infinity

• n(B) = 0

Multiple Choice

What is the cardinality of the set?

C = {a, b, c, d}

• n(C) = 4

• n(C) = 3

• n(C) = infinity

• n(C) = 0

Let's Compare

A = {0, 1, 2, 3}
B = {3, 2, 1, 0}
C = {a, b, c, d}

Equivalent Sets

Sets with same cardinality.
A = {0, 1, 2, 3}
B = {3, 2, 1, 0}
C = {a, b, c, d}

A ~ B read as "A is similar to B"
A ~ C read as "A is similar to C"

Equal Sets

Sets with same cardinality and elements.
A = {0, 1, 2, 3}
B = {3, 2, 1, 0}
C = {a, b, c, d}

A = B read as "A is equal to B"

Multiple Choice

Which among the following is equivalent to Set B?

B = {a, b, c}

A = {c, d, e}

C = {1}

D = { }

• A

• B

• C

• D

Multiple Choice

Which among the following is equal to set X?

X = set of even counting numbers

Y = set of odd counting numbers

Z = {2, 4, 6, ...}

W = {1, 3, 5, ...}

• X

• Y

• Z

• W

Summary

Equivalent sets are sets with same cardinality.

Equal sets are sets with same cardinality and elements.
