LENGTH OF UNEMPLOYMENT FOR WORKERS IN REGION X FOR TWO INDUSTRIES, 2003
Note
: The circle graphs show the distributions of workers who were unemployed for at least 1 week in 2003, by length of unemployment, rounded to the nearest week. [br] If one of the workers in the manufacturing and service industries who were unemployed for at least 1 week will be randomly selected, what is the probability that the person selected will be a service industry worker who was unemployed for 26 weeks or more?
选项
A、0.04
B、0.09
C、0.21
D、0.4
E、0.9
答案
A
解析
The probability that the person selected will be a service industry worker who was unemployed for 26 weeks or more is equal to the following fraction.
the number of service industry workers who were unemployed 26 weeks or more
the number of workers in the two industries who were unemployed at least 1 week
The number of workers in the two industries who were unemployed for at least 1 week is the sum of the total numbers of workers represented by the two graphs, or 10 million + 8 million = 18 million.
According to the graph for the service industry, the number of workers who were unemployed for 26 weeks or more is 9% of 8 million, or 0.72 million.
Therefore, the desired probability is
= 0.04. The correct answer is Choice A.
