a Compute the probability that none of the appeals will be successful Since there are only two outcomes this can be thought of as a binomial experiment Recall the binomial probability function below where x is the number of success p is the probability of a success on one trial and there are n trials probability A sample of 10 first round appeals have been received so we have n Let p be the probability that a first round appeal was successful It is given that 35 of first round appeals were successful This percentage must be converted to a probability as follows P Submit f x p 1 p x n x n x percentage 100 35 100 p n x where Of interest is the probability that none of the appeals will be successful Letting x be the number of successful appeals the probability that x Skip you cannot come back is to be found
