Question:

In Exercise 11.3.19 we saw that 42% of all Americans have type A blood. Assume five Americans are chosen at random. 

a. What is the probability that all of them have type A blood?

b. What is the probability that none of them has type A blood? 

c. What is the probability that at least one of them has type A blood?


Data from Exercise 11.3.19

It is estimated that 42% of all Americans have type A blood. Suppose two Americans are randomly selected (so the probability of one having type A blood is independent of the other). Find the probability of (a)–(c).
