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 2,3....10 . 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 f(2) + f(3) + ... + f(10) Submit Skip (you cannot come back)
(c)
Pr(atleast 2 successful appeals) = pr(exactly 2) + pr(exactly 3) ........................... + pr(exactly 10) ................(1)
Thus, x will take on values 2,3 ............10
If pr(exactly x successful appeals) = f(x)
From, (1) we have
=> Pr(atleast 2 successful appeals) = f(2) + f(3) + f(4) ............. f(10)
Thus, the answers are indeed correct
