Hi Tara,
in version 6 we have RandomSample that can take weights. We may choose
this to get one number with the weights you want. Using "Table" we then
get the array:
t=Table[RandomSample[{0.95,0.05}->{0,1},1][[1]],{30},{30}];
we can visualize this:
Graphics[Raster[t]] //Show
hope this helps, Daniel
