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.)
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 \(P=\frac{95}{171}=\frac{5}{9}\).
