Sets

Define what a set is in mathematics.

• A set in mathematics is a collection of identical objects

• A set in mathematics is a group of animals

• A set in mathematics is a type of fruit

• A set in mathematics is a collection of distinct objects.

Identify the elements in the set A = {1, 2, 3, 4}.

• {1, 2, 3}

• {2, 3, 4}

• {1, 3, 4}

• {1, 2, 3, 4}

How many subsets does the set B = {a, b, c} have?

• 12

• 8

• 10

• 5

Explain the difference between a set and a proper subset.

• A proper subset can have fewer elements than the original set

• In summary, a set can have the same elements as a proper subset, but a proper subset cannot have all the elements of the original set.

• A proper subset can have the same elements as the original set

• A set can have more elements than a proper subset

Write the set C in roster notation if C = {x | x is a prime number}.

• {2, 3, 4, 5, 6, ...}

• {1, 3, 5, 7, 9, ...}

• {2, 3, 5, 7, 11, ...}

• {2, 4, 6, 8, 10, ...}

Define what a subset is in relation to sets.

• A subset is a set that contains all elements from another set.

• A subset is a set that contains elements not found in another set.

• A subset is a set that contains elements in a random order.

• A subset is a set that contains only elements that are also in another set.
