Answer:

P(east) + P(west) = 0.12 + 0.18 = 0.3

So 0.3 is the correct answer.

Answer: 0.3

Step-by-step explanation:

From the given table, the probability that a person chosen at random, who lives in the city, lives in the East = [tex]\text{P(East)= 0.12}[/tex]

The probability that a person chosen at random, who lives in the city, lives in the West = [tex]\text{P(West)= 0.18}[/tex]

Since all the vents are independent .

Then, the probability that a person chosen at random, who lives in the city, lives in the East or West region is given by :-

[tex]\text{P(East or West)}=\text{P(East)+P(West)}\\\\=0.12+0.18=0.30[/tex]

Hence, the probability that a person chosen at random, who lives in the city, lives in the East or West region =0.3
