Answer: $\dfrac{5}{7}$

Step-by-step explanation:

Given

The theoretical probability of choosing an event A is $\dfrac{2}{7}$

The sum of the probability of occuring and non-occuring of an event is always equal to 1.

So, the probability of non choosing Event A is

$\Rightarrow 1-\dfrac{2}{7}\\\\\Rightarrow \dfrac{7-2}{7}\\\\\Rightarrow \dfrac{5}{7}$
