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).
The required probability that a randomly selected citizen, aged 25 or over, was a man with 4 years of college (or more) is 22\171.
Given that,
The educational attainment of a country's population, aged 25 and over.
Use the data in the table, expressed in millions,
We have to determine,
The probability that a randomly selected citizen, aged 25 or over, was a man with 4 years of college (or more).
According to the question,
There are 22 million males that have completed four years of undergraduate, according to the data below: (or more). This is predicated on a population of 171 million.
Then,
Probability randomly selected people = 22 million males that have completed four years of undergraduate ÷population of 171 million.
[tex]Probability = \dfrac{22 \ milion}{171 \ milion}\\\\Probability = \dfrac{22}{171}[/tex]
Hence, The required probability that a randomly selected citizen, aged 25 or over, was a man with 4 years of college (or more) is 22\171.
