Question

1. Over the past year, a university’s computer system has been struck by a virus at an average rate of 0.4 viruses per week. The university’s information technology managers estimate that each time a virus occurs, it costs the university $1000 to remove the virus and repair the damages it has caused. Assuming a Poisson distribution, what is the probability that the university will have the good fortune of being virus-free during the upcoming week? During this same week, what is the expected amount of money that the university will have to spend for virus removal and repair?

Answer 1

Since 0.4virus occurs per week and it cost the university $1000 to remove one virus.

There next week we expect to 0.4 virus and cost required will be =0.4×$1000. this will amount to $400
