Here is the probability model for the blood type of a randomly chosen person in the United States.

Blood type O A B AB
Probability 0.5 0.18 0.03 0.29

What is the probability that a randomly chosen American does not have type O blood?

% Round to the nearest 0.01%

what grade are you I go to connexus i am in 6th grade

prob not 0 = 1-prob(O)=.95

To find the probability that a randomly chosen American does not have type O blood, you need to subtract the probability of having type O blood from 1.

First, we find the probability of having type O blood by using the given probability model, which is 0.5.

P(Type O blood) = 0.5

To find the probability of not having type O blood, we subtract the probability of having type O blood from 1:

P(Not having type O blood) = 1 - P(Type O blood)
= 1 - 0.5
= 0.5

So, the probability that a randomly chosen American does not have type O blood is 0.5, which is equivalent to 50% or 0.50 when rounded to the nearest 0.01%.
