Hi Rex, Thanks for you explain. In fact, my question is: When I observed that there are 6 or more balls in one box, what is this probability? The ball is randomly put into the boxes. I think it is: 1-pbinom(6,142,1/491) = 2.272026e-08.
When the sample size is large, how should I do this? using chisq.test? Becuase binom test is not suitable for large sample size. For example, There are 6000 balls and 500 boxes, when I observed that there are 60 or more balls in one box, what is this probability?
