If we have a table with 100 buckets and 50 keys to put in those buckets, it is possible that all 50 of those keys could be assigned (hashed)to the same bucket in the table.However,someone who is experienced with using hash functions will tell you that you'd never see this in a million years. But that same person might also tell you that neither would you ever see. in a million years,all the keys hash into different locations.In fact,it is far less likely that all 50 keys would hash into one place than that all 50 keys would hash into different places,but both events are quite unlikely.Being able to understand just how likely or unlikely such events are is a major reason for taking up the study of probability. 间题2： 这里的you'd never..和neither would you ever.有什么意义？
