weeeeeb [17]

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

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