Question

Conjunction of :$2x+3=7$ $\to$ $x\ne 4$ is

• A. $2x+3=7$ $\wedge$ $x\ne 4$
• B. $2x+3=7$ $\leftrightarrow$ $x\ne 4$
• C. $2x+3=7$ $\vee$ $x\ne 4$
• D. $2x+3=7$ , $x\ne 4$

Answer 1

Answer: (A)

$2x+3=7$ $\wedge$ $x\ne 4$

Conjunction of two events means both of them occur simultaneously.

So, intersection of 2 statements is taken.

Here, statement 1 is: "$2x+3=7$", statement 2 is "$x\ne 4$"

Hence, option $A$ is correct.
