A multinomial experiment consists of 13 trials, where each trial has 3 possible outcomes. It's known that Outcomes 1,2, and 3 occur with probabilities = 0.5, P2 = 0.3, and P3 = 0.2 respectively. What is the probability that, over the 13 trials, Outcome 1 occurs exactly 4 times and Outcome 2 occurs exactly 3 times? (Your answer should be a decimal. Round to 4 decimal places if necessary.)
