Let event A = the place is a city let B = the place is in North America what is P(A and B)
A. 5/7
B. 3/7
C.4/7
D.2/7

Answer:
D. 2/7
Step-by-step explanation:
We assume that the intention is that one of the places is chosen at random from the list of 7 places.
2 of those are cities in North America, so the probability that a place randomly chosen from this list is a city in North America is ...
P(A & B) = 2/7
