Let A = {2, 3, 4, 5, 6, 7} B = {2, 4, 7, 8) C = {2, 4}. Fill in the blanks by ⊂ or ⊄ to make the resulting statements true.

B __ A

• ⊂

• ⊄

A = {x : x is a letter in the word SEAT}

B = {x : x is a letter in the word TASTE}

Determine if these two sets are equal or equivalent.

• Not equal because seat has 4 letters and taste has 5 letters.

• Equivalent because they have the same letters

• Equal because each set has the same cardinality and the same letters.

It is a collection of well-defined group of objects.

• Element

• Set

• Cardinality

• Universal Set

What is the cardinal of the set, H = {w, o, n, d, e, r, f, u, l}

• 10

• 9

• 8

• 7

Set C is the set of whole numbers less than 9. Write the set using the Roster method.

• C = {1, 2, 3, 4, 5, 6, 7, 8, 9}

• C = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

• C = {1, 2, 3, 4, 5, 6, 7, 8}

• C = {0, 1, 2, 3, 4, 5, 6, 7, 8}

Identify whether the following set is finite or infinite:

G = { ..., -2, -1, 0, 1, 2}

• Finite

• Infinite

• I have no idea
