10)In a blood testing procedure, blood samples from 6 people are combined into one mixture. The mixture willonly test negative if all the individual samples are negative. If the probability that an individual sample testspositive is 0.12, what is the probability that the mixture will test positive? A)0.00000299B)0.536C)1.00D)0.0144 2
11)A sample of 100 wood and 100 graphite tennis rackets are taken from the warehouse. If 14 wood and 13graphite are defective and one racket is randomly selected from the sample, find the probability that the racketis wood or defective. 12)If possible, determine whether the following is a probability distribution: A police department reports that theprobabilities that 0, 1, 2, 3, and 4 car thefts will be reported in a given day are 0.202, 0.323, 0.258, 0.138, and 0.055,respectively. 13)Suppose you pay $1.00 to roll a fair die with the understanding that you will get back $3.00 for rolling a 6,nothing otherwise. What is your expected value? 14)In a study, 42% of adults questioned reported that their health was excellent. A researcher wishes to study thehealth of people living close to a nuclear power plant. Among 14 adults randomly selected from this area, only 3reported that their health was excellent. Find the probability that when 14 adults are randomly selected, 3 orfewer are in excellent health.
