The school of music has two printers that students can use to print their work. The probability that a printer fails on any single day is 0.005. Failures occur independently. Any failed printers are repaired at the end of each day, so each day can be considered an independent trial.

(There is currently a lot of discussion about the fairness of this system, but universities get a lot of money from their alumni so they are unwilling...
