The probability of A and B is 3/7.
What is the probability?
Probability is a branch of math that deals with finding out the likelihood of the occurrence of an event.
A = Event that the place is a city
B = Event that the place is in North America
The first step is to get the sample space;
Let S represent the sample space;
Total number of cities = sample space = 7
The next is to list events A and B
Is a city = 5
North America = 4
n(city∩ north America) = 3
The probability of A and B is calculated as follows;
[tex]\rm Probability=\dfrac{n(A\ and\ B)}{n(s)}\\\\Probability=\dfrac{3}{7}[/tex]
Hence, the probability of A and B is 3/7.
