A credit card company monitors cardholder transaction habits to detect any unusual activity. Suppose that the dollar value of unusual activity for a customer in a month follows a normal distribution with mean $250 and variance $2409. What is the probability of more than $309 in unusual activity in a month? Round your intermediate calculations and final answers to four decimal places (e.g., 98.7654).
