Thread: Propability Homework Question

I've been working on my stats homework and have most of it done, however I am stuck on one question.

If the distribution of the continuous random variable x is known to be normal with a mean of 200 and a standard deviation of 10 find P(x=190). Explain how you arrived at your answer.

For a continuous distribution, Pr(X = a) = 0. It only makes sense to get the probability of X lying in an interval .......

Thank you, I knew it was something simple like that.
