Math Sets for Johanne

Well defined collection or group distinct objects

• Roster form

• Set builder form

• Sets

• Subset

Answer explanation

If the set is well defined, we can easily determined if an object belong to a set or not.

Elements are listed, separated by a comma and enclosed in a pair of brackets "{}"

• SINGLE FORM

• ROSTER FORM

• SET BUILDER FORM

• FINITE SET

Answer explanation

Remember, Roster form is separated by a comma "," and enclosed in a pair of brackets "{}"

A set is defined by skating the properly that describes all members of the set

• Roster Form

• Finite

• Infinite

• Set Builder form

Answer explanation

To remember it easily just remember 'the property that describes all members of the set"

"2,4,6..." What is the dots called?

• equal

• ellipsis

• Power sets

• equivalent

Answer explanation

the "..." is called ellipsis!

Same number of cardinality

• Equivalent

• Equal

• Power sets

• Singleton

Answer explanation

Just remember the 4 words "Same number of cardinality"

Contains exactly the same element

• INFINITE

• ELLIPSIS

• EQUAL

• SUBSET

Answer explanation

Remember, It contains EXACTLY the SAME ELEMENT.

What symbol is this from (C) and if all element of set A are also elements of set B, then A is a subset of B (Remember Lily said you just have to combine them together)

• Subset

• Proper Subset

• Power Sets

• Equal

Answer explanation

Lily said combine it together and that is the answer (I'm not sure)

if every element of a set A is a element of set B and set B has at least 1 element which is no A, the set is called?

• Singlegton

• Nullset

• Power Sets

• Proper Subset

Answer explanation

I dont know but "Example: If set A has elements as {12, 24} and set B has elements as {12, 24, 36}, then set A is the proper subset of B because 36 is not present in the set A."

Consist of all the subsets of p

• Equal

• Null set

• Singleton

• Power sets

Answer explanation

EXAMPLE I SAW FROM GOOGLE LOL: The empty set {} is a subset of {a,b,c}

• And these are subsets: {a}, {b} and {c}

• And these are also subsets: {a,b}, {a,c} and {b,c}

• And {a,b,c} is a subset of {a,b,c}

And altogether we get the Power Set of {a,b,c}:

P(S) = { {}, {a}, {b}, {c}, {a, b}, {a, c}, {b, c}, {a, b, c} }

set whose element are those which belong to set A or B, or to both sets

• Proper subset

• Difference of sets

• Union of sets

• Intersection of sets

Answer explanation

Remember, to form union you have to put together all the elements. ( A= [1,2,3,4] B= [1,2,3,5,6,2] so answer is 1,2,3,4,5,6.
