no...

you don't know what the Normal distribution is? I don't see how you can be trying these problems without knowing that.

$\large N(\mu,\sigma)=\dfrac{1}{\sqrt{2\pi}\sigma}e^{-\dfrac{(x-\mu)^2}{2\sigma^2}}$

and you can't just integrate it you have to look it up in a table or use software or something. You didn't go over any of this in class? It's not in your book at all?
