The director of a local blood bank is in need of a donor with type AB blood. The distribution of blood types for the blood banks region is estimated to be as shown in the table. The director decides that more than 20 donors are required before the first donor with AB blood appears, she will need to issue a special appeal for AB blood. Complete parts a and b. Type A B O AB Probability 45% 6% Click the icon to view the list of random blood types. a. Conduct a simulation 10 times, using the random blood types provided to estimate the probability this will happen The estimated probability to (Type an integer or a decimal. Do not round.) b. In praction, you would do at least 1000 simulations to estimate this probability wel. You'd then find that the probability of exceeding 20 donors before finding a type AB donor 0:28. Actually is not needed. Show how to find this probability by using the methods of this chapter Therefore, the probability can be written as the of the probabilities of 20 events that each have a probably which is 0.20 (Type an integer or a decimal. Do not round.) x the table. The director decides that with type A appears.
