\item Está lloviendo y hace calor. $\mapsto \ p \wedge q$\\
$p$: Está lloviendo\\
$q$: Hace calor\\

\item Nuestra bandera es blanca y celeste. $\mapsto \ p$\\
NOTA: La proposición es simple porque enuncia una sola caracteristica de la bandera, sus colores.
\item Marcos se dedica a la natación o al alpinismo. $\mapsto \ p \vee q$\\
$p$: Marcos se dedica a la natación.\\
$q$: Marcos se dedica al alpinismo.\\
\item El número 6 es mayor que el 3 y menor que el 7. $\mapsto \ p \wedge q$\\
$p$:El número 6 es mayor que el 3\\
$q$: El número 6 es menor que el 7\\
\item He pasado todas mis vacaciones en Grecia y Marruecos. $\mapsto \ p$\\
NOTA: La proposición es simple porque enuncia una sola caracteristica, los lugares donde pasó todas sus vacaciones.\\
\item Quiero salir, pero no puedo.$\mapsto \ p\  \wedge \sim q$\\
$p$: Quiero salir.\\
$q$: Puedo salir.\\
NOTA: Aunque el vocablo "pero" no es exactamente un conectivo lógico, sino más bien un adverbio de negación, en algunas ocasiones puede ser equivalente al conectivo conjuntivo "y" ($\wedge $).
\item La realidad supera a la ficción y él no puede creerlo. $\mapsto \ p\  \wedge \sim q$\\
$p$: La realidad supera a la ficción.\\
$q$: Él puede creer que la realidad supera a la ficción.\\
\item El televisor no funciona si no lo enchufas. CONTRAPOSITIVA: $ \sim q\  \Rightarrow \  \sim p$ de la proposición compuesta: \\
Si enchufas el televisor entonces el televisor funciona.\\
$ p\  \Rightarrow \ q$\\
$p$: Enchufas el televisor.\\
$q$: El televisor funciona.\\
\item No tenemos más alternativas.\\
Negación $\sim \ p$ de la proposición simple:\\
$p$: Tenemos más alternativas.
