(There are also some very rare blood groupings, such as Mumbai, Lutheran, Kell, and Kipp.) This is very important in medicine, since a person may die or suffer serious harm if they receive a transfusion from an incompatible donor. According to the Stanford University School of Medicine Blood Center, the distribution of blood groups/types in the United States is as follows: Blood Group A B AB 0 Total RH factor positive 714 170 68 748 RH factor negative 126 30 12 132 Total 1.a Complete the table by filling in the "total" row and the "total" column. 1.b Calculate P(blood group O) 1.c Calculate P( Group O and Rh positive) 1.d Calculate P( Group O or Rh-negative) 1.e Calculate P( Group O and Rh-negative ) 1.f Calculate P( not group A) 1.g Calculate P( Rh factor negative | group O ) h Is being blood group O independent of being Rh factor negative? 0 1 9 12:43E Gnogle Docs x | Q My Mission Portal-Home x Q:- Calendar x u HomeworkHelp-QAAfmmOnll xi + (- a C i hnps://wvm.instmcture.com/calendar#view,name=monih&view,sla$2021710708 homework 5.:locx A vase contains 8 purple balls and 4 yellow balls. Three balls are taken out of the vase on a random basis without replacement. What is the probability that all three balls selected are yellow? A recent report said that 40% of all California adults have a passport. Three California adults are selected at random. What is the probability that all three have a passport? (Since they are selected at random, and the population of California is huge compared to the sample size of 3, you can assume that whether one has a passport is independent of whether another has a passport.) A club with 50 members is going to elect a president, a vice president, a secretary, and a treasurer. Assuming that no person can be elected to more than one office, in how many ways can the selection be made? A clinic uses a diagnostic test to detect a certain disease. 2.5% (0.025) of all the patients at the clinic test positive, but just 0.4% (0.004) both test positive and actually have the disease. Given that a person tests positive what is the probability that they actually have the disease? A restaurant offers five entrees, three vegetables, six beverages and five desserts. Assuming that a person orders one item of each type, in how many different ways can the person order a meal?
