Question

The table below shows the educational attainment of a country's population, aged 25 and over. Use the data in the table, expressed in millions, to find the probability that a randomly selected citizen, aged 25 or over, was a man with 4 years of college (or more).

Answer 1

Answer:  22/171

Explanation:

The table shows there are 22 million men who have 4 years of college (or more). This is out of 171 million people total.

So the probability we want is (22 million)/(171 million) = 22/171

We cannot reduce that fraction any further because 22 and 171 do not have any common factors (other than 1).
