Question 1001263
41.  A given launch has a probability of a bad outcome of 5% and therefore a good outcome of 95%.  A good outcome is not in the critical direction.
42.  No cloud movement in critical direction is (0.95)^5=0.774, assuming independence.
43.  At least 1 is 1- probability of 0.  We already know that the probability of 0 for 5 launches is 0.774.  Therefore, the probability of at least 1 is 1-0.774=0.226 or 0.23.  You don't need to compute the probability of 2,3,4,5 bad outcomes for this problem.
44. Any 10 launches is the probability of 10 without subtracted from 1, as in the previous question.  (0.95)^10=0.599, so the probability of at least one bad outcome is 1-0.599=0.401 or 0.40.
