1. In a certain assisted living facility, the probability of patients contracting influenza is 0.20. Three patients are identified and monitored. Let X = number of patients that contract influenza.
   • a. Construct the probability distribution of the random variable, X
   • b. What is the probability that out of the three patients, one or less contracts influenza?
   • c. What is the probability that out of the three patients, two or more contracts influenza?
   • d. What is the probability that out of the three patients, less than two contracts influenza?
