(2) For the same Petri net, we consider a timed Petri net by making the delta time equal to 2 for al transitions (t1-L). Note we define delta time as: when transition ti (1-1,2,3,4) fires at time , it has to wait for at least time to fire again. Please specify the number of tokens in p-ps at time 1,2,3,4. Assume that the Petri net is currently specified at time 0. Put your answers in the Answer Book.
