A student is taking the online homework which allows at most 10 attempts and keeps attempting until passing the homework. Suppose each time the probability to pass is 0. 5, independent of the previous attempts. The student stops attempting the test once passing. Let X be the number of attempts to pass, and let A = {w | X(w) ≤ 10}. Provided that the student passed the homework, find the conditional PMF PXIA () of X and find (PX|A(3), PX|A (5)). = 0.1251,0.0313
