Expert Solution

When viewed from the highest to the most elemental level, the data hierarchy is typically organized as:

d. file, record, key.

Explanation:

At the highest level is the file, which is a collection of related records.

Each record contains a set of attributes (fields) that describe the characteristics of an entity or object.

The key is a unique identifier within each record that distinguishes it from other records within the file.

So, the correct sequence is file, record, key.

The correct answer is (d) file, record, key.

Suppose that a computer program randomly generates an 8-letter string from the letters A,B,C,D,E. For example, the program might generate the string CCCCCCCC or DAAEDCBB. The letter in each of the 8 positions is chosen independently of the other positions, and each of the five letters is chosen with equal likelihood. What is the probability that the string contains at least one A or at least one B?
