Answer:

Given by:

Given by the Probability of being a B+ holder as consider by =0.182

P (at least one is B+) given by =1-P (none is B+)

                                                  =1-(1-0.182) ^14

                                                        =0.9399

The American Red Cross was founded in 1881, blood types were first identified in 1901 but the first blood bank in the United States was not established until 1932. The blood type distribution in the U.S. is type A: 40%, type B: 10%, type AB: 4%, type O: 46%. Some of the first large-scale use of blood transfusions was to save the lives of the injured during World War II. At that time errors in matching the donors blood with...

Your insurance company has converage for three types of cars. The annual cost for each type of car can be modeled using Gaussian (Normal) distribution, with the following parameters: Car Type 1: Mean=$520 and Standard Deviation=$110 Car Type 2: Mean=$720 and Standard Deviation=$170 Car Type 3: Mean=$470 and Standard Deviation=$80 Use the Random number generator and simulate 1000-long columns, for each of the three cases. Example: for the Car Type 1, use Number of variables=1, Number of random numbers=1000, Distribution=Normal,...
