Suppose that a random variable X follows a normal distribution with mean 10 and variance 25. Let Z be a random variable following the standard normal distribution. You are interested in the probability that X is greater than 18. After standardization, what probability it will become? O a Pr(Z-0.4) Ob. Pr(2>1.6) OC Pr(Z>2) Od Pr(2>1.2) O e Pr(Z>1)
