36 of 80 teachers at a local school are certified in CPR. In 180 days of school, assuming none of the teachers were ever absent, about how many days is it that the teacher on bus duty will likely be certified in CPR?(adsbygoogle = window.adsbygoogle || []).push({});

Can someone give some idea of how to solve this problem.

I notice that they want the probability that "the teacher on bus duty will likely be certified in CPR". So it is the probability of one teacher.

I did 180/36 =5 days. But I don't think that is write. I am currently learning discrete probability distributions.

I hope someone can help. Thanks
