Sheet1 Page 1 They will have less than five unfilled orders 94.7347% of the time. P(X = 0) = 0.13533528 P(X = 1) = 0.27067057 P(X = 2) = 0.27067057 P(X = 3) = 0.18044704 P(X = 4) = 0.09022352 Hypergeometric distribution with parameters N = 9, M = 4, n = 3. According to the "January theory," if the stock market is up for the month of January, it will be up for the year. If it is down in J a What is the probability this could occur by chance? (Round your answer to 6 decimal places.) ---------------------- The probability is (1/2) for each year.
