@tomleslie  thanks ..The command "unapply" was the solition of my problem ;) Thanks

@acer  Thanks for this option

@mmcdara 

Thank you for this series of tracks. The only problem is in the final rendering for 'not A' 'not B'.. I think it’s the 2020 version.

@mmcdara  I tested another idea ( with permute) which seems good for my expectation

Thanks for your time !

I tried it with X and it didn’t work. My goal is to generate probabilities , to make my students work on simple empirical distributions

@mmcdara  Thanks for this idea.

There is a way to have the fractional form for the X elements ?

@Kitonum  I thought about this solution. But I try to vary the values of V. negative and positive elements. Thanks

@Kitonum  I want to generate "probabilities" values..so , only positive values?

Ideas ? Thanks

@Carl Love 

Finally, it’s better with InertForm package

Thank you for your informative feedback. My basic idea is purely didactic: Generate to my students different statistical series in which, the first column, represents the notes obtained during an exam
