Answer:
To find the probability that two people do not have blood type O, we can use the binomial probability formula:
P(x) = (n choose x) * p^x * (1 - p)^(n - x)
Where:
n is the number of people (5 in this case)
x is the number of people who do not have blood type O (2 in this case)
p is the probability of an individual having blood type O (0.25 in this case)
Plugging in the values, we get:
P(2) = (5 choose 2) * (0.25)^2 * (1 - 0.25)^(5 - 2)
= 10 * 0.0625 * 0.54
= 0.3375
So the probability that two people do not have blood type O is approximately 0.3375.
