The figure shown represents a board with 4 rows of pegs, and at the bottom of the board are 4 cells numbered 1 to 4.Whenever the ball shown passes through the opening between two adjacent pegs in the same row, it will hit the peg directly beneath the opening.The ball then has the probability 1/2 of passing through the opening immediately to the left of that peg and probability 1/2 of passing through the opening immediately to the right.What is the probability that when the ball passes through the first two pegs at the top it will end in Cell 2?
