Example Questions
Example Question #1 : Logic
over the domain
For all
which is true?
This question is giving a subset
who lives in the domain and it is asking for the partition or group of elements that live in both and .Looking at what is given,
it is seen that both four and seven live in
and therefore both these elements will be in the partition of . Another element that also exists in both sets is the empty set.Thus the final solution is,
Example Question #1 : Theory Of Positive Integers
Negate the following statement.
is a prime number.
is not a prime number
is an odd number
is a prime number
is an even number
is not a prime number
is not a prime number
Negating a statement means to take the opposite of it.
To negate a statement completely, each component of the statement needs to be negated.
The given statement,
is a prime number.
contains to components.
Component one:
Component two: "is a prime number"
To negate component one, simply take the compliment of it. In mathematical terms this looks as follows,
To negate component two, simply add a "not" before the phrase "a prime number".
Now, combine these two components back together for the complete negation.
is not a prime number.
Example Question #3 : Theory Of Positive Integers
Determine which statement is true giving the following information.
is a prime number is odd
None of the answers.
To determine which statement is true first state what is known.
The first component of this statement is:
is a prime number
This is a true statement since only one and seventeen are factors of seventeen.
The second component of this statement is:
is odd
This statement is false since
.Therefore, the only true statement is the one that uses the "or" operator because only one component is true.
Thus the correct answer is,
Example Question #4 : Theory Of Positive Integers
over the domain
For all
which is true?
This question is giving a subset
who lives in the domain and it is asking for the partition or group of elements that live in both and .Looking at what is given,
it is seen that only ten lives in
and therefore both these elements will be in the partition of . Another element that also exists in both sets is the empty set.Thus the final solution is,
