Question

Suppose that type A blood is needed from donors. If 40% of donors have type A blood and you want to estimate the probability that it will take at least four donors to find one with type A blood, how could you simulate a blood donor having or not having type A Blood?

Answer 1

Step-by-step explanation:

If 40% of donors in a population have type A blood, then the probability of finding a type A blood donor is;

40/100 = ¼

It will take at least four donors to find one with type A blood because we add the probabilities of the individuals which will give us a 1. We add probabilities in a union of events

¼ + ¼ + ¼ + ¼ = 4/4 = 1

A probability of 1 a complete certainty chance

Answer 2

Answer:

0, 1, 2, 3 could represent type A blood, and 4, 5, 6, 7, 8, 9 could represent non-type A blood.

Step-by-step explanation:

A random digit is a good simulation to use for this situation. 0, 1, 2, 3 could represent type A blood, and 4, 5, 6, 7, 8, 9 could represent non-type A blood.
