The … WebShad0w2751 • 1 min. ago. Either would work but in this situation a binomial (10, 0.1) distribution makes the most sense as the car can’t break down multiple time on one day. If you know the car can break down multiple times in a day then poisson is more appropriate. I would use a poisson (3) distribution if that were the case.
