The National Center for Health Statistics (NCHS) reports that 70% of U.S. adults aged 65 and over have ever received apneumococcal vaccination. Suppose that you obtain an independent sample of 20 adults aged 65 and over who visited theemergency room and the pneumococcal vaccination rate applies to the sample.Determine the probability that exactly 12 members of the sample received a pneumococcal vaccination. Let X represent thenumber of successes in a binomial setting with n trials and probability p of success in each trial. The probability of obtainingexactly k successes is given by the formulaP(X = k} = (")* - pr-*where () is the binomial coefficient, also represented as ,C, and is defined asn!k!(n - k)!Follow the steps to compute P(X = 12). First determine the binomial coetlicient. Do not round your answer.20 Ci2 =Compute (.7), or the probability that exactly 12 adults have been vaccinated. Round your answer to six decimal places. (7)2 =Compute (.3)*, or the probability that exactly 8 adults have not been vaccinated. Report as a decimal to eight decimal places. Donot round.(.3)Compute P(X = 12) = 20C12 · (,7)2 .
