12. 66% of adults cannot name a supreme court justice. You randomly select five adults and ask each if they can name any of the justices. The random variable represents the number of adults who cannot name a Supreme Court justice. Complete parts (a) through (d) beld (a) Find the mean of the binomial distribution. (Round to two decimal places as needed.) (b) Find the variance of the binomial distribution. 0= (Round to two decimal places as needed.) (c) Find the standard deviation of the binomial distribution. = (Round to two decimal places as needed.) (d) What values of the random variable would you consider unusual? Explain your reasoning. On average, out of 5 adults cannot name a supreme court justice, with a standard deviation of adults. The values x=0 and x= would be unusual because their probabilities are (1). 0.05. (Type integers or decimals rounded to two decimal places as needed.) (1) less than O equal to more than
