a. List the properties of a binomial random variable. b. According to an​ almanac, 80​% of adult smokers started smoking before turning 18 years old. ​         1.  Compute the mean and standard deviation of the random variable​ X, the number of smokers who started before 18 in 200 trials of the probability experiment. ​         2.  Interpret the mean. ​         3. Would it be unusual to observe 180 smokers who started smoking before turning 18 years old in a random sample of 200 adult​ smokers? Why? https://aacc.mylabsplus.com/
