Question

the table shows the educational attainment of the population of a country, ages 25 and over, expressed in millions. find the probability that a randomly - selected person, aged 25 or over, has completed four years of high school only or some college, but less than four years

| |

years of high school	years of college	total
less than 4	4 only	some (less than 4)	4 or more
male	13	24	25	22	84
female	16	26	20	25	87
total	29	50	45	47	171

the probability is
(type an integer or a simplified fraction.)

Explanation:

Step1: Identify relevant values

The number of people who completed four - year high school only is 50 million, and the number of people who have some college (less than 4 years) is 45 million. The total population is 171 million.

Step2: Calculate the number of favorable outcomes

The number of favorable outcomes (people who completed four years of high school only or some college but less than four years) is \(50 + 45=95\) million.

Step3: Calculate the probability

The probability \(P\) is the number of favorable outcomes divided by the total number of outcomes. So \(P=\frac{95}{171}=\frac{5}{9}\).

Answer:

\(\frac{5}{9}\)
