Question

The probability distribution table shows the proportion of people living in the five different regions of a city.

Answer 1

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 = $\text{P(East)= 0.12}$

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

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 :-

$\text{P(East or West)}=\text{P(East)+P(West)}\\\\=0.12+0.18=0.30$

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

Answer 2

Answer:

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

So 0.3 is the correct answer.
