Answer:

1/21

Step-by-step explanation:

The probability of finding the first person without a license is 2/7. When he is "eliminated" there will be one less person out of the 7 (so 6 people in total left), and only one person without a license. the new probability is now 1/6. You then multiply these 2 fractions. 1/6 times 2/7= 1/21. The probability that the inspector will pick the 2 without a license is 1/21
