The required probability is 0.6704.
Explanation of Solution
Given information:
The data:
Highest education | Total population | In labor force | Employed |
Didn’t finish high school | 27,669 | 12,470 | 11,408 |
High school but no college | 59,860 | 37,834 | 35,857 |
Less than bachelor’s degree | 47,556 | 34,439 | 32,977 |
College graduate | 51,582 | 40,390 | 39,293 |
Calculation:
Know that probability can be calculated by dividing the number of favorable outcomes by the number of possible outcomes.
To find the required probability, divide the sum of all people in labor force by the total population.
Thus, the required probability is:
Hence, the required probability is 0.6704.
