Answer:
D: 2/7
Explanation:
The probability of an event x is how likely the event will occur. It is given as;
P(x) = number of expected outcomes / number of possible outcomes
Given:
Event A = The place is a city.
Therefore,
P(A) is the probability that the event A happens. i.e the probability that a place is a city.
P(
) is the probability that the event A does not happen. i.e the probability that a place is not a city
Also,
The sum of the probability that an event happens and the probability that the event does not happen is equal to 1. i.e
P(A) + P(
) = 1
From the table,
P(
) is found by counting the number of places that does not have a tick on the "is a city" column, then divide the result by the total number of places. i.e
P(
) = 2 รท 7
P(
) = 2/7
Therefore P(
) which is the probability that the place is not a city is 2/7
