Math Problem Statement
A random variable has a triangular probability density function with a = 50, b = 375, and m = 250.
What is the probability that the random variable will assume a value greater than 330? If required, round your answer to four decimal places.

PDF: f(x) = 2(x - a) / ((b - a)(m - a)) for a ≤ x ≤ m, f(x) = 2(b - x) / ((b - a)(b - m)) for m ≤ x ≤ b
CDF: F(x) = 1 - (b - x)^2 / ((b - a)(b - m)) for m ≤ x ≤ b
P(X > x) = 1 - F(x)
