INSTRUCTIONS Overview Thinking in systems allows you to view problems as parts of a whole and gives you a tool set to address those problems. In this activity, you will use your knowledge of systems thinking methodologies to analyze a scenario and map the relationships between the parts of a system. Prompt To successfully complete this activity, address the following: Define the following systems-thinking concepts in your own words: Define systems thinking, providing an example of how this is used in the IT field. Describe collections and how they are distinguished from systems. Define feedback loop, providing an example of how this is used in the IT field. Define stock and flow diagram, providing an example of how this is used in the IT field. Define casual loop diagram, providing an example of how this is used in the IT field. The following scenario describes the system used for fulfilling an online order at Lost Pines Outfitters, a medium-sized outdoor clothing store. Read this scenario and create a basic map of the system using Microsoft Visio. Lost Pines Outfitters (LPO) Online When a customer places an order through LPO's online portal, the order is sent directly to the warehouse, where an associate takes (pulls) the selected items from warehouse shelves. Warehouse associates use a single computer to track incoming orders, locate items in inventory, and pull inventory for fulfillment. Once LPO's warehouse associates have pulled the items from inventory, they manually update the inventory tracking system and the item is sent to the fulfilment department. In the fulfillment department, associates package the items for delivery to customers and assign the shipment a tracking number through the U.S. Postal Service. Once the order has shipped, an associate in LPO's fulfillment department manually checks the tracking information and updates the order's delivery status. Once the customer receives the order, an associate sends a card, thanking them for their purchase and requesting they leave a review of the item and their experience shopping with Lost Pines Outfitters. Once you have mapped this system, you will map relationships contained within the system. First, identify relationships within your system diagram that represent feedback loops, and represent those loops within your model. Then, identify a relationship within the system that could be modeled with a stock and flow or causal loop diagram, and model that diagram in Visio. Compose a brief, 250- to 500-word summary of the given system as well as the interactions and relationships present in the system. What to Submit Upload a Word document that must include your written descriptions and your diagram of the system.

A new restaurant would like to investigate if different age groups of customers prefer different types of food items. Each of their customers is given a food item - a burger or a sandwich. Each customer belongs to either adult or child age group. The customers were then surveyed on whether they enjoyed the food item. The table below gives the percentage of customers in each category.

(a)The product rule (also called the chain rule)states that:P(X1,X2,,Xn)=P(X1)P(X2|X1)P(X3|X1,X2)..P(Xn|X1,X2,,Xn-1)Now,prove the above rule in reverse direction as stated below:P(X1)P(X2 I X1)P(X3 | X1,X2)...P(Xn|X1,X2,...Xn-1)=P(X1,X2,...,Xn)(b)Prove that zeDomain()P(A=B=b)=1,where Domain(A)represents all thevalues that the random variable A can take,and the random variable B is assigned toits value b.

Due to the small size of mobile screens, it is common for users to mistype their words when texting or emailing over phone. Hence, to increase the usability of the apps, it is important to automatically correct or suggest a corrected version of the mistyped words. We can identify the correct word in the following way. For a given mistyped word w, we can generate multiple candidate words that could be correct, and evaluate each candidate c using the Bayes' rule.
