Use the data in the following table, which summarizes blood groups and Rh types for randomly selected subjects.
Use the data in the following table, which summarizes blood groups and Rh types for randomly selected subjects. Assume that subjects are randomly selected from those included in the table.
If one person is selected, find the probability of getting someone who is Group A or type Rh+. Are the events of selecting someone who is Group A and the event of someone who is type Rh disjoint events?
The probability of getting someone who is Group A or type Rh+ is _______
Homework Answers
Solution:-
P(Getting someone who is in group A or type Rh+)
= (42 + 30 + 5 + 7+ 8)/(42 + 30 + 5 + 7+8+8+4+1)
= 0.8762
No, the events (Group A and Type Rh+) are not disjoint because they can occur at the same time.
