Justine Ho · Answer 1

480 applicants

Step-by-step explanation:

Firstly, we were told 80% will pass the written test. This means out of those 1000 people, 800 people will pass the written test. That us established according to the information.

Secondly, we were told that 60% of those who passed the writing test

passed the driving test and eventually got the license.

Thus, we evaluate 60% of 800 and this equals 480.

Hence, in a random sampling of 1000 candidates according to previously generated data, 480 would be expected to receive their driving licenses.
