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.

	years of high school		years of college		total
male	11	27	19	18	75
female	13	27	24	24	88
total	24	54	43	42	163

the probability is \boxed{}. (type an integer or a simplified fraction.)

Explanation:

Step1: Find total population

The total population aged 25 or over is 163 (from the "Total" row and "Total" column).

Step2: Find number who completed 4+ college

The number of people who completed four years (or more) of college is 42 (from "Total" row and "4 or more" column).

Step3: Find number who did not complete 4+ college

Subtract the number who completed 4+ college from total population: \( 163 - 42 = 121 \).

Step4: Calculate probability

Probability is number of favorable outcomes (not completed 4+ college) divided by total outcomes: \( \frac{121}{163} \).

Answer:

\(\frac{121}{163}\)
