Question

A blood bank asserts that a person with type O blood and a negative Rh factor (Rh?) can donate blood to any person with any blood type. Their data show that 43% of people have type O blood and 19% of people have Rh? factor; 45% of people have type O or Rh? factor.1.) Find the probability that a person has both type O blood and the Rh? factor.2.) Find the probability that a person does NOT have both type O blood and the Rh? factor.

Answer 1

Answer:P(O)UP(Rh)=17% while n(O)U(Rh) complement is 87%

Step-by-step explanation:

Since 43% represent those blood group O and 19% those with blood Rh,summing up gives 62%

Subtract 45% from 62%=17%

The probability that the person doesn't have either blood group is1 -17%=83%

Answer 2

Answer:

The probability that a person has a positive Rh factor given that he/she has type O blood is 82 percent.

There is a greater probability for a person to have a Positive Rh factor given type A blood than a person to have a positive Rh factor given type O blood.
