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

what is the probability that a person chosen at random, who lives in the city, lives in the east or west region?

question 3 options:

0.06

0.12

0.18

0.3

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 =

The probability that a person chosen at random, who lives in the city, lives in the West =

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 :-

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

The answer to your question is there are 440 students

Step-by-step explanation:

Data

110 girls = 25% of the total students

The Total number of students = ?

Use a rule of three to solve this problem

                    110 girls 25%

                      x            100%

                      x = (100 x 110) / 25

                      x = 440 students
