Use a truth table, to prove each rule of logic.

$$\begin{array}{l} p \\ \hline p \vee q \end{array}$$

A condition is given in which you stand on the seat of a chair and then hop off. During the time you are in flight down to the floor, your logic. The Earth moves up through a distance of what order of magnitude? In your solution, explain your logic. Model the Earth as a perfectly solid object.

Draw the logic circuit represented by each of the following expressions: (a) A + B + C + D (b) ABCD (c) A + BC (d) ABC + D

Answer “true” or “false” to the following statements: From the standpoint of logic, many definitions are concerned not with words but with things.

We need a logic circuit that gives a high output if a given hexadecimal digit is 4, 6, C, or E. The inputs to the logic circuit are the bits $B_8, B_4, B_2$ and $B_1$ of the binary equivalent for the hexadecimal digit. (The MSB is $B_8,$and the LSB is $B_1.$ Construct the Karnaugh map and write the minimized SOP and POS expressions for X.

A stairway light is controlled by two switches-one at each end of the stairs. If the switches are both up or both down, then the light is on. Otherwise, it is off.

a. Make a table showing whether the light is on or off for every possible combination of switch positions. (Let "on" $=1$ and "off" = 0.)

b. Draw a logic network that represents when the light is on.

c. Write a logical expression for this network.

Rearrange the premises to form a chain of if-then statements, and give a conclusion based on the premises. You may replace statements with their contrapositives.

$$\left\{\begin{array}{l}\text { Everyone with brown hair can do logic. } \\ \text { Everyone without brown hair is fit to serve on a jury. } \\ \text { None of your brothers can do logic. }\end{array}\right.$$

Translate each of the following sentences into symbolic logic. For every positive number $\mathcal{e}$ there is a positive number M for which $|f(x)-b|<\varepsilon$, whenever $x>M$.

A __________ error does not prevent the program from running but causes it to produce incorrect results. a. syntax b. hardware c. logic d. fatal

Use propositional logic to prove that the argument is valid. $(A \rightarrow B) \wedge[A \rightarrow(B \rightarrow C)] \rightarrow(A \rightarrow C)$

Use propositional logic to prove the arguments valid. $(P \rightarrow Q) \wedge\left(P^{\prime} \rightarrow Q\right) \rightarrow Q$

Use propositional logic to prove the validity of the arguments. $(P \rightarrow Q) \rightarrow\left(Q^{\prime} \rightarrow P^{\prime}\right)$
