. United Blood Services is a blood bank that serves more than 500 hospitals in 18 states. According to their website, a person with type O blood and a negative Rh factor (Rh-) can donate blood to any person with any blood type. Their data show that 43% of people have type O blood and 15% of people have Rh- factor; 52% of people have type O or Rh- factor. a) Find the probability that a person has both type O blood and the Rh- factor. b) Find the probability that a person does NOT have both type O blood and the Rh- factor. b)

In a study of 320,354 cell phone users, it was found that 34 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000142 probability of a person developing cancer of the brain or nervous system. We therefore expect about 46 cases of such cancer in a group of 320,354 people. Estimate the probability of 34 or fewer cases of such cancer in a group of 320,354 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system? (a) P(xs 34)= H(Round to four decimal places as needed) (b) What does the result from part (a) suggest about the media reports? O A. The media reports appear to be correct because one would expect that less than 46 cell phone users would develop cancer and the study offers some evidence to support this O B. The media reports appear to be incorrect because one would expect that more than 46 cell phone users would develop cancer In fact, the study may offer some…
