Berkat Health Insurance wishes to introduce a new insurance policy for smokers. They conducted a study to know at what age adult smokers usually acquired their smoking habit. They found that one out of five adult smokers acquired the habit at age 21. If 400 smokers are randomly selected, write the random variable for above probability problem and find the probability that at most 85 of them acquired the habit at age 21. ii. i. the probability for less than k adult acquired the habit at age 21 is 10.5%, determine the value of k.
