What is the truth value of the following statement? 10 is a perfect square

False

What is the truth value of the following conditional? If there are 48 hours in a day then there are 60 minutes in a second.

True

What is the truth value of the following conjunction? 1 is a prime number and 15 is divisible by 5

False

Given: p: 13 is an odd number q: is a rational number What is the truth value of the following: pV q

True

Given: k: the grass is green m: the sky is purple What is the truth value of: k m

False

What is the truth table for conjunction:

pq p ∧ q TTT TFF FTF FFF

What is the truth table for disjunction?

pq p ∨ q TTT TFT FTT FFF

Which of the following has the same truth value as the given statement: Given: 4 + 1=7 and 3 + 2= 5 a)4 + 1=7 or 3 + 2= 5 b)If 4 + 1=7 then 3 + 2= 5 c)4 + 1 ≠ 7 if and only if 3 + 2= 5 d)4 + 1=7 or ≠ 5

D

Given the true statement, “John likes math or John likes science,” and the true statement, “John does not like science.” What is the truth value of John does not like math?

False

Which of the following has the same truth value as the original statement: 12 is a prime number or 7 is a prime number a)12 is not a prime number and 7 is a prime number b)12 is a prime number and 7 is not a prime number c)12 is a prime number or 7 is not a prime number d)12 is a prime number and 7 is a prime number

A

What is the truth table for the conditional?

pq p ⇒ q TTT TFF FTT FFT

Which of the following is an example of a biconditional? a)If it rains then I get wet b)It rains and I get wet c)It rains or I get wet d)It rains if and only if I get wet

D

Which value of x makes the statement, If x < 10 then x is a perfect square false? a)36c) 4 b)6d) 25

B

Given the false statement, “If Rachel passes her classes then Rachel plays basketball.” Determine the truth value of “Rachel passes her classes and Rachel does not play basketball”

True

True or False: 81 is a perfect cube if and only if 8 is a perfect square

True

What is the inverse of “ If I go to homecoming then I will ride in a limo?

If I do not go to homecoming then I do not ride in a limo

Write the statement that is logically equivalent to: If I go to work then I will get paid

If I do not get paid then I will not go to work

Which of the following is the converse of “ If a triangle has three sides then it is a polygon? a)If a triangle does not have three sides then it is not a polygon b)If a triangle is not a polygon then it does not have three sides c)If a triangle is a polygon then it has three sides d)If a triangle has three sides then it is not a polygon

C

Which of the following statements is logically equivalent to “If I eat breakfast then I will pay attention? a)If I do not pay attention then I did not eat breakfast b)If I do not eat breakfast then I do not pay attention c)If I pay attention then I ate breakfast d)If I do not pay attention then I ate breakfast.

A

Write the inverse, converse, and contrapositive of the following statement AND the truth value of each If 4 is even then 7 is odd.

Inverse: if 4 is not even then 7 is not odd (true) Converse: If 7 is odd then 4 is even (true) Contrapositive: If 7 is not odd then 4 is not even. (True)

Write the symbol for each of the following? A)Disjunction B)Conjunction C)Conditional D)Biconditional

A) V B) Λ C) D)

Given the following statements: “I will go to college if and only if I work” (T) “I do not work “(T) Find the truth value of, “I will go to college”

False

Given the false statement, “Mary falls asleep or she watches a movie” and the true statement “Mary does not watch a movie.” What is the truth value of Mary falls asleep? Justify your answer!

Mary falls asleep is false because we are told that the statement, “Mary falls asleep or she watches a movie is false,” and the only way for a disjunction to be false is if both statements are false.

Give an example of a value for x that makes the statement, “x is prime or x > 7”, false.

a)Kevin does his math homework and his mother is angry. b)Kevin does not do his math homework or his mother is not angry. c)If Kevin’s mother is angry, then he did not do his math homework.
