Final answer:
The specific percentage of physicians served by McKesson is not provided; we only have the percentage of services offered to business/nonprofit sectors, other educational institutions, medical schools, and those in independent practice.
Step-by-step explanation:
The percentage of physicians McKesson serves is not explicitly provided in the given information. However, we can discuss the sectors McKesson is involved with based on the information given:
- Business or nonprofit organizations constitute 10%.
- Other educational institutions make up 8% of their service range.
- Medical school engagement stands at 6%.
- Those in independent practice are also at 6%.
To determine the specific percentage of physicians served by McKesson, one would need additional information that details what proportion of their services are directed toward physicians specifically. This might include direct partnerships with medical facilities, or the distribution of medical supplies and pharmaceuticals to healthcare professionals.
