The figure below shows a social network where the nodes represent social media influencers,and the lines are the cost of investing in promoting digital links between the nodes. However,for the brand to remain viral, your client, which is a digital advertising firm needs to maintain aconnection between influencers number 1 and 12 through other influencers. a. If you wish to recommend your client to choose the digital route from influencer 1 toinfluencer 12, which route would you recommend to your client and why? Pleasedemonstrate your results through any optimization.b. Using the same Figure 1 above but this time the node represents a project undertakingand arcs represent the expected profit (in million £) after completing one project andstarting another, what would be the ideal project sequence to maximise the company’sprofit?Note: For instance, selecting path Node 1 to Node 2 denotes “after completing project 1and starting project 2, the firm expects to gain a profit of £2…

A manufacturer of DVD players purchases a particular microchip, called LS-24, from three suppliers: Hall Electronics, Schuller Sales, and Crawford Components. 30% of the LS-24 chips were purchased from Hall Electronics, 20% from Schuller Sales, and the remaining 50% from Crawford Components. The manufacturer has extensive track records on all three suppliers and knows that 3% of Hall Electronics' LS-24 chips are defective, 5% of Schuller Sales' LS-24 chips, and 4% of Crawford Components' LS-24 chips are defective. defects. When LS-24 chips arrive at the manufacturer, they are placed directly in a warehouse and are not inspected or identified with the supplier's name. A worker selects a chip to install in a DVD player and finds it defective. What is the probability that it was made by Hall Electronics? What is the probability that Crawford Components made it? What is the probability that it was made by Schuller Sales?
