The following data lists the number of correct and wrong dosage amounts calculated by 34 physicians. in a research experiment, a group of 19 physicians was given bottles of epinephrine labeled with a concentration of "1 milligram in 1 milliliter solution," and another group of 15 physicians was given bottles labeled with a ratio of "1 milliliter of a 1: 1000 solution." if one of the physicians is randomly selected, find the probability of getting one who made a correct dosage calculation or was given the bottle with a concentration label.
