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.)
