(c)What is the probability that at least two of the appeals will be successful?
Let x be the number of appeals that are successful. Therefore, if there are at least two successful appeals, then x will take on the values ---Select--- 2,3,...10 3,4,...10 0,1,2 0,1 . Let f(x) be the probability of exactly x successful appeals. The probability of at least two successful appeals in a sample of 10 will then be ---Select--- f(2) + f(3) + ... + f(10) f(3) + f(4) + ... + f(10) f(0) + f(1) + f(2) f(0) + f(1) .
