shading an area under the normal curve

Hi,

Is it possible to do with Mathcad of Mathcad Prime?

1: shade the area the encompasses the inner 68 % of the normal probability distribution, that is +/- 2 standard deviation from the mean.

2: shade the probability (0.212) that a random variable is below 360 with a mean of 400 and standard deviation of 50 pertaining to a normal distribution.

If yes, how?

Thank you very much!

Johny.
