Question

At the Blood Bank, they know that O+ blood is the most common blood type and that 40% of the people are known to have O+ blood. Blood type A- is a very scarce blood type and only 6% of the people have A- blood. Half of the people have blood type A or B

Let:

  • X= number of people who have blood type O+
  • Y= number of people who have blood type A-
  • Z= number of people who have blood type A or B

please answer a) b) and c) 

a)
Consider a random sample of n
8 people who donated blood over the past three months.
The expected number of people with blood type O+is
and the expected number of people with blood type A-is
Round your answers to 2 decimal places.
Calculate the following probabilities:
o P(X = 2)
Round your answer to 4 decimal places.
o P(X > 2) -
Round your answer to 4 decimal places.

Expert Solution
Step 1

As per our guidelines, we are allowed to answer first three sub-parts \

 

P( O+ ) = 0.4

P( A-) = 0.06

P( A or B) = 0.5

  • X= number of people who have blood type O+
  • Y= number of people who have blood type A-
  • Z= number of people who have blood type A or B
