Question 1047062: People with type O-negative blood are referred to as universal donors, although if you give type O-negative blood to any patient you run the risk of a transfusion reaction due to certain antibodies present in the blood. However, any patient can receive a transfusion of O-negative red blood cells. Only 5.3% of the American population have O-negative blood. If 8 people appear at random to give blood, what is the probability that at least one of them is a universal donor? (Use 4 decimal places.)

Hi
Recommend Using stattrek.com to check Your results
until You are familiar with Using Your Calculator.
1) One could also Use A Casio fx-115 ES plus 0r fx-991 ES plus.
In a similar fashion..: Mode: DIST(binomial PD).
2) TI syntax is binomcdf(n, p, largest x-value) for binomial ≤ cumulative probability
3) TI syntax for P(x-value) is binompdf(n, p, x-value).0*** appropriate here
P = .053 , n = 8
1 p(X >= 1) = 1 - binompdf(8,.053,0) = 1 - .6468
