Task2: Please share a piece of code that visualizes the probability that Fred is indeed infected as the dependent variable, with the infection prevalence (5% in the example above, which takes any real-number value between 0.001% to 50%) and the specificity (99% in the example above, which takes values 99%, 99.9%,99.99%, and 99.999%) as independent variables. For simplicity, we fix the sensitivity at 99%. Visualize the results if possible, and use integers to check and explain your results. Use any programming language that you prefer. Please put your code in GitHub or GitLab or other code-hosting service and paste the link below. *
