9. Suppose that 45% of the U.S population has Type O blood, 40% Type A, 11% Type B, and the rest is Type AB. Among the 3 donors answer the following. i) Describe the multiplication rule for any two independent events. Write the events first ii) P(none are Type B) = iii) P(exactly 1 to have type B) = iv ) P(exactly 2 are type B) = V ) P(exactly 3 are type B) = vi) P(At least one is Type B) = vii) Now take 4 donors. List the possibilities to have Type A. Show the corresponding probabilities
