Mathematica does it simply like this

Can Maple do it similarily easily?  how?

I have a list of sample values and I want to remove just one maybe two of them. 

list:=[13,16,16,29,34,33,33,12,22,26,25,25,25,11]:

How could I remove just one 25 from the list? 

Is there a difference between these two? 

with(Statistics):

Sample(Normal(0,1),100)

Sample(RandomVariable(Normal(0, 1)), 100)

How to generate a random normal distribution of points around the point [3,15] for example?

Does Maple have something similar to c-means clusteirng in Matlab?

 How would I go about doing something like this in Maple?
