Probability of O & AB Blood Types

In summary, out of 200 people, 40 have type A blood, 75 have type B blood, 60 have type O blood, and 25 have type AB blood. The probability of randomly selecting a person with type O blood is 30%, and the probability of selecting a person with type AB blood is 12.5%.

  1. The blood groups of 200 people are distributed as follows: 40 have type A blood, 75 have type B blood, 60 have type O blood, and 25 have type AB blood. If a person from any of the group is selected at random, what is the probability that this person has an O blood type? How about the AB blood type? i hope you will help me.

Do you not know the basic definition of probability? You are told that, out of 200 people, 60 have type O blood. 60 is what percent of 200? You are told that, out of 200 people, 25 have type AB blood. 25 is what percent of 200?
 

FAQ: Probability of O & AB Blood Types

What is the probability of having an O blood type?

The probability of having an O blood type is approximately 44% in the general population. This means that roughly 4 out of 10 people will have an O blood type.

What is the probability of having an AB blood type?

The probability of having an AB blood type is approximately 4% in the general population. This means that only about 1 out of 25 people will have an AB blood type.

Is there a connection between O and AB blood types?

Yes, there is a connection between O and AB blood types. O is considered the universal donor, meaning that those with O blood type can donate to any other blood type. AB is considered the universal recipient, meaning that those with AB blood type can receive blood from any other blood type.

Can a child have a different blood type than their parents?

Yes, it is possible for a child to have a different blood type than their parents. This is because blood type is determined by genetics, and a child can inherit different blood type alleles from their parents.

What factors can affect the probability of having a certain blood type?

Some factors that can affect the probability of having a certain blood type include genetics, ethnic background, and geographical location. For example, certain blood types are more common in certain ethnicities or regions.
