A hоspitаl is cоnducting а twо-stаge screening process for a rare disease. The disease prevalence in the population is 1%. The screening process consists of: Test 1: A preliminary test that correctly identifies diseased individuals 85% of the time (sensitivity) and incorrectly flags 15% of healthy individuals as positive (false positive rate). Test 2: A confirmatory test that is administered only to those who test positive in Test 1. It has a sensitivity of 98% and a false positive rate of 2%. A patient receives a positive result from both tests. What is the probability that they actually have the disease? Model the process using simulation. You need to create a template yourself for this problem. Rename it under your name before submitting it.

The following table shows the capacity of each lot Lot Capacity Total number of faculty and staff parking pass holders LOT A 250 310 LOT B 300 345 LOT C 350 400 The number of people showing up in each lot is independent of the others. On a typical day, the probability of a LOT A parking permit holder showing up is 85%, a LOT B parking permit holder showing up is 87%, and a LOT C parking permit holder showing up is 89%. Suppose the parking pass holders are allowed to park in any of LOT A, LOT B, and LOT C. What is the probability that on a typical day, at least one parking permit holder will be unable to find a parking space? You need to build a simulation model to answer this question.

Jake’s car dealer is trying to determine how many model 2024 cars to order. Each car ordered in September costs $45,000. The demand for the new electric cars has the following probability distribution. Each car sells for $54,000. If the demand for 2024 cars exceeds the number of cars ordered in September, Jake must reorder at a cost of $50,000 per car. Excess electric cars can be salvaged at $39,000 per car. Cars demand Probability 25 0.25 30 0.20 35 0.15 40 0.20 45 0.20 Assume Jake orders 60 cars in September. What is Jake’s average profit? Please build a simulation model to answer this question.
