Question 185

Multiple Choice

Write the compound statement in symbols. Then construct a truth table for the symbolic statement.
Let r = ʺThe food is good,ʺ p = ʺI eat too much,ʺ q = ʺIʹll exercise.ʺ
-If the food is not good, I won?t eat too much.


A) (rp) \sim(r \rightarrow p)
rp(rp) TTFTFTFTFFFT\begin{array} { c c c } \mathrm { r } & \mathrm { p } & \sim ( \mathrm { r } \rightarrow \mathrm { p } ) \\\hline \mathrm { T } & \mathrm { T } & \mathrm { F } \\\mathrm { T } & \mathrm { F } & \mathrm { T } \\\mathrm { F } & \mathrm { T } & \mathrm { F } \\\mathrm { F } & \mathrm { F } & \mathrm { T }\end{array}

B) (rp) \sim(r \rightarrow p)

C) rp\sim \mathbf{r} \rightarrow \sim \mathrm{p}
