Use the data in the following​ table, which summarizes blood groups and Rh types for randomly selected subjects.

Assume that the selections are made with replacement. Are the events​ independent?   The probability is nothing. The events ▼   are not are independent because the occurrence of the first subject having blood type Rh+ ▼   does does not affect the probability of the occurrence of the second subject having blood type Rh+. ​(Round to three decimal places as​ needed.)
