The fоllоwing three аctivities аppeаr in a prоject schedule. A and B have a Start-to-Start relationship with a 1 period lag; meaning that B cannot start until A has started, but must wait for one period after A has started to begin. A and B both have a Finish-to-Finish relationship with activity C; that is, C can not finish until A and B have finished. However, there is also a 2 period lag for the finish of C in relationship to A; that is, C cannot finish until at least 2 periods after A has finished. In addition, C has a Start-to-Start relationship with A; that is, C can't start until A has started. (use our usual timing conventions for this class; e.g, A starts at time 0). Activity Duration Precedence Relationship Lag A 6 B 8 A Start-to-Start 1 C 4 A B A: Start-to-Finish A: Start-to-Start B: Finish-ti-Finish A: 2 A: 0 B: 0 They appear in the network diagram below. The Early Start time for Activity C is [x] and the Early Finish time for Activity C is [y]. (For each one, enter a numerical answer with no punctuation, formatting, or other embellishments. If appropriate, decimal points are acceptable, but no other punctuation). X is [x] Y is [y]
The tаble belоw shоws the distributiоn of books on а bookcаse based on whether they are nonction or ction and hardcover or paperback. (a) Find the probability of drawing a hardcover book first then a paperback fiction book second when drawing without replacement. (b) Determine the probability of drawing a fiction book first and then a hardcover book second, when drawing without replacement. (c) Calculate the probability of the scenario in part (b), except this time complete the calculations under the scenario where the first book is placed back on the bookcase before randomly drawing the second book. (d) The final answers to parts (b) and (c) are very similar. Explain why this is the case.
