Research has shown that 55% of new Small Medium Enterprises (SMEs) are started by graduates while 45% are started by non-graduates. It is also shown that 70% of SMEs started by graduates are successful i.e. they survive beyond 3 years, while 10% of those started by non-graduates are successful. If it is know that the new SME is not successful, what is the probability that it was not started by a graduate?
15. (Disease test): According to the clinical records, the accuracy rate of a certain cancer diagnosis test is 95%, that is, the probability of cancer patients being diagnosed with cancer and the probability of healthy people being told to be healthy are both 95%. Now, the general survey in natural population is carried out, and the prior probability of the tested person suffering from cancer is 0.006. Find out the probability of the diagnosed person suffering from cancer when the test results are known to be positive. (Let A="the test reaction is positive" and C= "the diagnosed person has cancer")

According to a recent study, more than 900 people move to Florida each day! In fact, data show that only 34% of current Florida residents were born in Florida. Let ˆpp^ be the proportion of people who were born in Florida out of a random sample of 219 Florida residents. Determine the following probabilities. Round solutions to four decimal places, if necessary.Find the probability that in a random sample of 219 Florida residents, less than 35% were born in Florida.P(ˆp<0.35)=P(p^<0.35)=Find the probability that in a random sample of 219 Florida residents, between 27% and 39% were born in Florida.P(0.27<ˆp<0.39)=P(0.27<p^<0.39)=
The probability of the Dow Jones index rising on the first day of trading next week is thought to be 0.6. If it does rise then the probability that the value of shares in a publishing company will rise is 0.8. If the index does not rise then the publishing company’s shares will only have a 0.3 probability of rising. What is the probability that the publishing company’s shares will rise in value on the first day of trading next week?
