Probability Density Function

Hello,

I have graphed a normal probability density function with a mean of 10 and a 
standard deviation of 2.5.  I named this function f[x]

I wanted to know how to use the "FilledPlot" to show the area under the 
curve for (x<8) and (7.5<x<11).

I have the probability for x<8 to be .212 and for 7.5<x<11 to be .497 by 
calculating the definite integral of the function f[x] for these two 
probabilities.

I have the cacluation of the probabilities included but no idea on how to 
continue and display each of these in a graph.

Thanks,

T Harris
