Question
The following data lists the number of correct and wrong dosage amounts calculated by 29 physicians. In a research experiment, a group of 14 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. P(physician made a correct dosage calculation or was given the bottle with a concentration label) = (Type an integer or decimal rounded to three decimal places as needed.)
Explanation / Answer
Probability that the physician made a correct dosage calculation or was given the bottle with a concentration label
= ( number of physicians making correct dosage calculation + number of physicians given bottle with concentration label - number of physicians making correct dosage calculation and given bottle with concentration label ) / Total number of physicians
= ( 15 + 14 - 12 ) / 29
= 0.586
Therefore 0.586 is the required probability here.
