Question

A Place from this table is chosen at random. Let event A= The place is a city. what is P(Ac)?

Answer 1

Okay, here we have this:

How The probability of an event is a ratio that compares the number of calculating favorable outcomes with the number of possible outcomes. We obtain:

$P(A^C)=\frac{numberof\text{cities}}{numberofplaces}=\frac{4}{7}$

Finally we obtain that the correct answer is the option B.
