The diagram below depicts a 4-step Binomial tree to model share price. In a riskneutral world, the probability (p) of share price moving up on any given branch of the tree is 0.4778. There are several paths that lead to a final share price of $30. What is the probability that share price starts at $30 and finishes at $30? Enter your answer to 4 decimal places. For example, if your answers is 12.34%, enter 0.1234
