Answer 1

Probability that the books will be in the correct order = (1/479001600)

Step-by-step explanation

The probability of an event is calculated as the number of elements in the event divided by the total number of elements in the sample space.

For this question,

Number of orders that will be in the correct order = 1

Total number of ways 12 volumes of the book can be ordered = 12! = 479,001,600

Probability that the books will bein the correct order = (1/479001600)
