Discrete random variable X has possible values 2, 6, 10, 14, 18, and 22

Discrete random variable X has possible values 2, 6, 10, 14, 18, and 22. Continuous random variable Y has density function f(y) = y/288, if 0 < y < 24 and f(y) = 0 otherwise. If Y is a good approximation for X, find Pr[6 ≤ X ≤ 18].
