ANSWER:
2/7
STEP-BY-STEP EXPLANATION:
The complement event is the probability that complements the given event up to 100%, that is, up to 1.
We know that the probability is calculated by dividing the number of favorable outcomes by the total.
Therefore, the probability of the complete event would be:
[tex]\begin{gathered} P(A)=\frac{\text{ cities}}{\text{ places}}=\frac{5}{7} \\ \\ P(A^c)=1-\frac{5}{7}=\frac{2}{7} \end{gathered}[/tex]
Therefore, The correct answer is option A. 2/7
