Here are some hints to get you started. Let me know what you think.
If the mean number of bugs in 1 minute is 0.0001, what is the mean number of bugs in 20 minutes?
Can you take a guess as to what probability distribution the number of bugs in a certain time period is? Do you know a distribution related to counting how many events occur in a given time period?
