We are expected to find 1,080,000 right handed people in that group of people

Step-by-step explanation:

In this question, we are given the ratio of right handed to left handed people and we are asked to calculate the number of right handed people we can find in a given population.

First, we check the ratio given.

The ratio is said to be that of left handed individuals to right handed individuals and this sits at 2 to 9.

Thus out of 1,320,000 people , the number of right handed individuals will be ;

9/(2+9) * 1,320,000

9/11 * 1,320,000

= 1,080,000 people
