Example Question #1 : 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 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 #2 : Logic
Negate the following statement.
is a prime number.
is not a prime number
is an odd number
is an even number
is a prime 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 : Logic
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 : 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 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,
