An company tracks their workplace accidents. They determine that each month, the probability of no workplace accidents is 0.80 and the probability of one or more workplace accidents in a month is 0.2. After the 3rd month with at leaset one workplace accident, the company will conduct mandatory safety training. Hint: In this scenario, a month with an accident is a “success” and accident free months are “failures”. The distribution for the variable of the number of accident free months before the third month with an accident. Determine the expected number of months between trainings (i.e. determine the expected value of the distribution) Determine the probability that the company will conduct training sometime between and including 11 and 13 months.
