shading an area under the normal curve

[jsuarez]

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.

Maybe that way. The plottype of the second plot is "Column Trace".

It should be obvious how to change mean, std deviation and upper/lower limit at will.
