blood Group and Types If 2 of the 100 subjects are randomly selected, find theprobability that they are both group o and type Rh+ a. Assume that the selections are made with replacement b. Assume that the selections are made withoutreplacement Group O A B AB TypeRh+ 3935 8 4 Rh- 6 5 2 1 blood Group and Types If 2 of the 100 subjects are randomly selected, find theprobability that they are both group o and type Rh+ a. Assume that the selections are made with replacement b. Assume that the selections are made withoutreplacement Group O A B AB TypeRh+ 3935 8 4 Rh- 6 5 2 1Explanation / Answer
Group O A B AB Total
TypeRh+ 3935 8 4 86
Rh- 6 5 2 1 14
Total 45 40 10 5 100
Probability for with replacement:
Prob(group 0 and type Rh+)=prob(select 2 fromgroup0)+prob(select 2 from type Rh+)-Prob(select 2 from group 0Union type Rh+)
Here total
(45C2+86C2-39C2)/100C2=0.788687
Probability for without replacement.
(45P2+86P2-39P2)/100P2=0.788687
