A simplified model for the movement of the price of a stock supposes that on each day the stock's price either moves up 1 unit with probability 0.35 or moves down 1 unit with probability 0.65. The changes on different days are assumed to be independent. What is the probability that after 11 days the stock's price will have increased by exactly 1 units? Give your answer to 4 decimal places.
