Students go out of the Evans Hall and go to either left or right. Assume that each student chooses to go left with probability 0.4 independently of all other students. You start watching the students at the exit of the Evans Hall. Find the chance that you have seen at least 10 students going to the left before seeing the first student going to the right? O (10) 0.49 x 0.6 O _ 10 0.41-1 x 0.6 O 0.410 = 1 0.41-1 x 0.6
