just need help with these two please:)

Consider the assembly line bolow. The three fabrication operations nun in paratlel, such that each batch of 20 units cnly noeds to go through one of the three fabrication operationi. After that, each batch needs to go through both assembly cperations, which ocour simultaneously (specifically. some components for each urit are asspmbled in the Assnmbly 1 area while others are aspembled in the Assembly 2 ares). The units are packaged and made ready for shipment in the final stage. What is the bottleneck time per batch of this operation? A. 8min B. 10min. c. 6 min. D. 5min. E. 16min. F. 54 min. G. 7min. H. 4min 1. 2min A local projoct being analyzed by PERT has 42 activitios, 13 of which are on the critical path. If the estimated time along the critical path is 105 dayss weth a groject variance of 25 . Whan is ife probability that the projoct will be completed in 95 days or more? A. =0.40000 B. 4.20000 C. 0.34444 D. 0.97725 E. 0.02275 \begin{tabular}{|c|} \hline Fabrication \\ 18 nin/bat ch \\ \hline \end{tabular} Fabrication18mn/batch Fabrication18min/batch
