Consider the following statements
$P :$ Suman is brilliant
$Q :$ Suman is rich
$R :$ Suman is honest
The negation of the statement "Suman is brilliant and dishonest if and only if Suman is rich" can be expressed as
$\; \sim \left( {{\rm{Q}} \leftrightarrow \left( {{\rm{P}} \wedge {\rm{\;}} \sim {\rm{R}}} \right)} \right)$
$ \sim {\rm{Q}} \leftrightarrow {\rm{\;}} \sim {\rm{P}} \wedge {\rm{R}}$
${\rm{\;}} \sim \left( {{\rm{P}} \wedge {\rm{\;}} \sim {\rm{R}}} \right) \leftrightarrow Q$
$\; \sim P \wedge \left( {{\rm{Q\;}} \leftrightarrow \sim {\rm{R}}} \right)$
$p \Rightarrow q$ can also be written as
Which of the following Venn diagram corresponds to the statement “All mothers are women” ($M$ is the set of all mothers, $W$ is the set of all women)
Which of the following is the inverse of the proposition : “If a number is a prime then it is odd.”
If statement $(p \rightarrow q) \rightarrow (q \rightarrow r)$ is false, then truth values of statements $p,q,r$ respectively, can be-
The Boolean expression $\left(\sim\left(p^{\wedge} q\right)\right) \vee q$ is equivalent to
