Question

the table shows the educational attainment of the population in a certain country, ages 25 and over, expressed in millions. find the probability that a randomly selected person, aged 25 or over, has not completed four years (or more) of college.
the probability is (type an integer or a simplified fraction.)

Explanation:

Step1: Find the number of people who have not completed four years (or more) of college

The total number of people is \(155\) million.
The number of people who have completed \(4\) or more years of college is \(34\) million.
So the number of people who have not completed four years (or more) of college is \(155 - 34=121\) million.

Step2: Calculate the probability

The probability \(P\) of an event is given by the formula \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\).
Here, the number of favorable outcomes (people who have not completed four years (or more) of college) is \(121\) and the total number of outcomes (total population aged 25 or over) is \(155\).
So \(P = \frac{121}{155}\)

Answer:

\(\frac{121}{155}\)
