O-negative blood is considered universal for transfusions, with only 7.2% of Americans having this blood type. The probability that at least one out of ten randomly chosen individuals is a universal donor is approximately 53%. This is calculated by finding the complement of the probability that none of them are universal donors.

People with O-negative blood are universal donors. That is, any pati.pdf
- 1. People with O-negative blood are universal donors. That is, any patient can recieve tansfusion of O-negative blood. Only 7.2% of the American population have O-negative blood. If 10 people appear at random to give blood, what is the probablity that at least 1 of them is universal donor? Solution 10C0 * .072^ 0 * .928^10 = 0.473674235 This is the probability that NONE of them are the universal donor. It turns out, the event we are interested in, is just the compliment. Then 1 - 0.473674235 = 0.526325765 Hence, 53% probability.
