Mr. Gordon’s science class is studying blood types. The table below shows the probability that a person living in the US has a particular blood type.

Question

the probability of having a blood type: O= 9/20; A= 41/100; B= 1/10; and AB= 1/25
What is the probability that three students selected randomly from the class will have A, B, and AB blood, respectively?

or 1.64%

or 0.17%

or 0.16%

or 31.9%

Answer 1

To find the probability that three students selected randomly from the class will have blood types A, B, and AB respectively, we multiply the probabilities of each blood type together:

(41/100) * (1/10) * (1/25) = 41/2500 = 0.0164 = 1.64%

So, the probability that three students selected randomly from the class will have A, B, and AB blood types respectively is 1.64%.

Therefore, the correct answer is 1.64%.
