Answer:

B

Step-by-step explanation:

Number A is wrong because 180-20-65 does not equal 90

Number B is right because x is equal to 180-90-65 which does not equal 90

We do not have to consider any more.

What is a probability that a person chosen at random who lives in the city live in the east or west region?
Anastasy [175]

<u><em>Answer:</em></u>

0.3

<u><em>Explanation:</em></u>

We are given that:

Probability that a randomly chosen person lives in the East is 0.12

P(East) = 0.12 ..................> I

Probability that a randomly chosen person lives in the West is 0.18

P(West) = 0.18 ............> II

Now, we want to find the probability that the randomly chosen person lives in the East or West

<u>To do this, we will use the following formula:</u>

P(A or B) = P(A) + P(B)

<u>Applying this rule to our givens:</u>

P(East or West) = P(East) + P(West)

P(East or West) = 0.12 + 0.18

P(East or West) = 0.3

Hope this helps :)
