3rd subsection

The third subsection "Conventions Used in This Book" details the typographical conventions. All examples are in italic, while probably only the first and the last should be, because otherwise the second and the forth example are identical.

Chapter 1, section "Risk Assessment"

The chapter 1 contains an image of a 5 by 5 risk matrix in the section "Risk assessment". In the last row "Rare", the last two entries should probably be 4 and 5 instead of 5 and 6 in order to maintain the symmetry.

Other Digital Version I. MLOps: What and Why - Risk Assessment
Figure 1-4.

Dear Reader,
I would like to thank you for this wonderful book. I really enjoyed reading it.

My question relates to figure 1-4. In this matrix, the risk is based on the probability and the impact of adverse events.
I have a question about the calculation of matrix elements.
I understand that the matrix assigns the numbers 1-5 to each level of impact and probability.

Impact levels are:
Very Low: 1
Low: 2
Medium: 3
High: 4
Very High: 5

Probability levels are:
Rare: 1
Unlikely: 2
Possible: 3
Probable: 4
Highly Probable: 5

Each element is calculated by multiplying the impact level by the probability level. Based on my assumption, "High Impact, Rare Probability" and "Very High Impact, Rare Probability" should have a result of 4 and 5.
However, the book lists the results as 5 and 6.
I would appreciate it if you could explain how they are calculated. Or am I correct in my assumption?

Thank you in advance!
