Applications of Probability

Suppose you and your classmates are surveying some of the employees working at your company. The company has over 10,000 employees, so you each collect information from a sample of 500 employees to get some insight into how vulnerable the company may be to external threats, or hacks, to the computers used by employees. You will use your survey results along with probability to assess the companies’ risk. Please include the following information:

1. Compute and clearly state the probability (as a decimal and percentage) for each of the following:
   • A company employee has not run a computer security scan in the past 60 days.
   • A company employee has not installed the latest patches to the operating system on their computer.
   • A company employee has not installed the latest patches to the operating system on their computer and has run a computer security scan in the past 60 days.
   • A company employee has installed the latest patches to the operating system on their computer and has not run a computer security scan in the past 60 days.
2. Express the likelihood of a security breach at your company — high, moderate, or low — based upon insight you gained from computing probabilities from the survey results. In one or two sentences, discuss how this analysis of empirical probability may be beneficial to you and your company.
