Question

What is the probability that a randomly selected person surveyed has a job, given that the person is less than 18 years old? Explain your answer and show your work!

Answer 1

The probability is 20/607 or about 3 %

Answer 2

When the person is less than 18 years old, out of 265 persons, 20 has job and 245 do not have job.

The probability is defined as $\frac{no\;of \; favourable \;outcomes}{total\;number\;of\;outcomes}$.

Consider the first column only.

The probability that a randomly selected person surveyed has job is

$\frac{20}{20+245} =0.0755$
