Question

use the pie chart at the right, which shows the number of workers (in thousands) by industry for a certain country. find the probability that a worker chosen at random was not employed in the services industry.
the probability is
(round to three decimal places as needed.)

Explanation:

Step1: Calculate total number of workers

Total workers \(=1661 + 2762+11279+115541\)
\(=131243\) (in thousands)

Step2: Calculate number of non - services workers

Non - services workers \(=1661 + 2762+11279\)
\(=15702\) (in thousands)

Step3: Calculate probability

Probability \(P=\frac{\text{Non - services workers}}{\text{Total workers}}\)
\(P = 1-\frac{115541}{131243}\)
First, \(\frac{115541}{131243}\approx0.880\)
Then \(P=1 - 0.880=0.120\)

Answer:

\(0.120\)
