Suppose we were to add a third (concurrent) process of “eat cookie” to our situation, as depicted in Figure 3 — draw out the resulting composition of the three concurrent processes “drink coffee”, “think → talk” and “eat cookie” Recall the "coffee with a friend" situation, involving the two (concurrent) processes depicted in Figure 1startdrink coffee0start (0,0)think(0, 1)Figure 1: Two concurrent processes that are happening while having coffee with a friendtalkstartThe composition of these two processes would be as given in Figure 2 The composition is somehowthe "product" of these processes, and is a complete representation of this concurrent system. Its nodesrepresent the possible states that the system can be in, e.g., (1, 1) represents that I already drank mycoffee, while I have thought about what to say, but have not said it yet. The edges give the possibletransitions between these (composite) states, and so each path from the initial state (0, 0) to the finalstate (1,2) represents a possible trace of this system, e.g., think→ drink coffee → talk.drink coffeestartdrink coffeedrink coffee(0, 2)0think(1,2)eat cookie0talktalk(1, 1)2thinkFigure 2: The composition of the two concurrent processes of Figure 1(1,0)One could imagine yet a third process happening concurrently to the first two, as depicted in Figure 3.while having coffee with a friend. Again, one cannot eat a cookie while drinking coffee, thinking or talking(or should not?), but any of these can happen in any order, with the exception that one must think beforetalking, as constrained by the second process depicted in Figure [1]Figure 3: Another possible (concurrent) process among those of Figure 1

According to the information given:- We have to follow the instruction in order to perform above task.As given, some figures are added by me for making a little easier to understand the answers. all answers are created on given figure. Figure :1 These the process that is use in figure 2 by combining these process states. Figure: 2 This process is created by using above two process . based on the figure: 3 as below, since, There is not given more information . Because I read the full question so we will create figure:3 by using 3 process "\drink coffee" , "\think !talk" , "eat cookie" . since, there are given that one cannot eat a cookie while drinking coffee , thinking or talking . And also we know based on the above question node (1, 1) These (1,1) represents that i already drank my coffee . That means that one cannot eat a cookie before above process which given in figure:1 . Figure: 3
