1. In Fig. 2-2, three process states are shown. In theory, with three states, there could be six transitions, two out of each state. However, only four transitions are shown. Are there any circumstances in which either or both of the missing transitions might occur?

Step-by-step explanation:

Given points:

3, 2.25,  opposite of 4, -(-1 1/2) ⇒ 3, 2.25, -4, 1 1/2

In ascending order:

-4, 1.5, 2,25, 3

Using o,25 intervals:

-4.00, -3.75, --3.50, -3.25, -3.00, -2.75, -2.50, -2.25, -2.00, -1.75, -1.50, -1.25, -1.00, -0.75, -0.50, -0.25, 0, 0.25, 0.50, 0.75, 1.00, 1.25, 1.50, 1.75, 2.00, 2.25, 2.50, 2.75, 3.00

Plotted tick marks

-4.00, 1.50, 2.25, 3.00

Number of marks

between: -4.00 and 1.50 = 21between: 1.50 and 2.25 = 2between: 2.25 and 3.00 = 2
