3. Suppose, the social network estimates the average number of duplicate accounts is 11 of monthly active users. Suppose X is the randomly selected account. a. What is the distribution X ? Give a justification of your answer. b. What is the probability that fewer than two accounts are duplicate in a randomly selected accounts among the monthly active users? c. What is the probability that exactly none of the accounts are duplicate in a randomly selected accounts among the weekly active users? d. Find the (Mean ± Standard deviation) interval for monthly active users and hence comment this interval.
