Question 26. There is a rate of 1 cyberattack per every 39 seconds. A computer scientist is in charge of observing 3 randomly chosen computer systems to record whether the system has had 2 attacks per second. (a) Write the sample space of the observation experiment of this computer scientist and determine the probabilities of each outcome. (b) Write down, showing the work needed to understand where your numbers come from and their relation to the sample space, the probability mass function of the number of computer systems among those observed that have had 2 attacks per second. (c) A cyberattack has a cost of 150 million dollars. A cyberattack costs 150 million dollars. What is the expected cost and standard deviation of the cost of cyberattacks based on your findings?
