A) mean = np
0.6(200) = 120
SD^2= np(1-p)
SD = sqrt(200(0.6)(1-0.6))
SD = 6.928
B) the mean of binomial distribution in this case is the average number of samples you’ll have to take before you achieve a sample of 200 where 60% of smokers who started smoking before 18.
X=25 and u would add 5x to both sides 6x=25+5x then u would multiply both sides by 0.25 making it 1.5x=6.25+1.25x
