Question

The four blood types bellow are genetic phenotypes that are mutually exclusive events. Of 5400 individuals examined, the following frequency of each blood type is observed.

4. What is the relative frequency of each blood type?

5. Assuming that each of 5400 individuals has an equal opportunity of being encountered.

a)Estimate the probability of encountering a person with type A blood.

b)Estimate the probability of encountering who has either type A or type AB blood.

PLEASE SHOW WORK ON HOW YOU CAME UP WITH THE ANSWER.

Explanation / Answer

4. Relative frequency of O = 2672/5400

Relative frequency of A = 2041/5400

Relative frequency of B = 486/5400

Relative frequency of AB = 201/5400

5. a) P(A) = 2041/5400 = 0.378

b) P(A or AB) = (2041+201)/5400 = 0.415
