Asimplified model of the human blood-type system has four blood types: a, b, ab, and o. there are two antigens, anti-a and anti-b, that react with a person’s blood in different ways depending on the blood type. antia reacts with blood types a and ab, but not with b and o. anti-b reacts with blood types b and ab, but not with a and o. suppose that a person’s blood is sampled and tested with the two antigens. let a be the event that the blood reacts with anti-a, and let b be the event that it reacts with anti-b. classify the person’s blood type using the events a, b, and their complements.

Blood type will be A when event "A" happened and event "B" did not happen. Blood type will be B when event "A" did not happened and event "B" happened. Blood type will be AB when both events happened and blood type will be O when both events did not happen.

Step-by-step explanation:

S={AntiA reacts; AntiA does not react; AntiB reacts; AntiB does not react}

If AntiA reacts and AntiB reacts = AB (A∩B)

If AntiA does not react and AntiB does not react= O (A'∩B')

If AntiA reacts and AntiB does not react= A (A∩B')

If AntiA does not react and AntiB reacts= B (A'∩B)
