Suppose \(X\) represents the annual rainfall (in millimeters) in a coastal city, and it follows a normal distribution with a mean of 1200 mm and a standard deviation of 150 mm. Calculate the probability that the annual rainfall exceeds 1350 mm. Round your answer to two decimal places.
\(P(X \geqslant 1350) \approx\)
