Question

A place from this table is chosen randomly. Let event A = the place is a city. What is P(A^c)?

Answer 1

Thus  P(A^c) = 1 - P(A) = 1- 5 / 7 = 2 / 7

Option (A) is correct.

Step-by-step explanation:

Here,

Sample space = S = {Rome, Tokyo, Houston, Peru, Miami, Toronto, Canada}

So, |S|=7

Event A = The randomly selected place is a city.

A = {Rome, Tokyo, Houston, Miami, Toronto}

So, |A|=5

Hence,

P(A) = |A| / |S| = 5 / 7

Then, A^c be the event that the randomly selected place is not a city, so

P(A^c) = 1 - P(A) = 1- 5 / 7 = 2 / 7
