If $y$ is normal distribution random variable with mean $\mu = 10$ and standard deviation $\sigma = 2$ . $z$ is standard normal variable and $F(Z)$ is cumulative distribution function, then which of the following are true?

[Given that $F(1.5) = 0.9332$ , $F(3) = 0.9986$ , $F(2.25) = 0.9878$ and $F(1) = 0.8413$ ]

(A) $P(X < 13) = 0.9332$

(B) $P(X > 16) = 0.9986$

(D) $P(X > 8) = 0.8413$
