Answer

Answer:

12

Explanation:

Step1: Count total digits

There are 20 digits in the given random - number sequence (4 groups of 5 digits each: 5×4 = 20).

Step2: Count digits representing free food

Count the number of digits from 0 - 6 in the sequence 21274 37971 35532 28153. The digits representing free food are: 2, 1, 2, 4, 3, 3, 5, 5, 3, 2, 8, 1, 5, 3. There are 12 such digits. So the best estimate of the number of free - food prizes won by the next 20 patrons is 12.
