Question

Here is the probability model for the blood type of a randomly chosen person in the United States.Blood typeoАBABProbability 0.42 0.21 0.07 0.3What is the probability that a randomly chosen American does not have type o blood?% Round to the nearest 0.01%

Answer 1

The total probability = 0.4 + 0.21 + 0.07 + 0.3 = 1

Given that the probability that a randomly chosen American has a type O blood is 0.42, then, the probabillity that a randomly chosen American does not have a type O blood is

1 - 0.42 = 0.58

= 58 x 100 = 58%
