The Office of Student Affairs receives numerous appeals from students seeking reevaluation of their enrollment status. The office has observed that, on average, 30% of appeals are successful. Suppose the office has recently received 15 appeals. Calculate the probability that none of the appeals will be successful. Determine the probability that exactly three appeals will be successful. Find the probability that at least two appeals will be successful. At least two appeals means P(x≥2). Compute the probability that less than half of the appeals will be successful. Less than half means P(x<8) or P(x≤7).
