RandomChoice[wlistelist,n]
gives a list of n weighted choices.

RandomChoice[wlistelist,{n1,n2,}]
gives an ×× array of weighted choices.

DetailsDetails

  • RandomChoice[{e1,e2,}] chooses with equal probability between all of the .
  • RandomChoice gives a different sequence of pseudorandom choices whenever you run the Wolfram Language. You can start with a particular seed using SeedRandom.
  • A Method option to SeedRandom can be given to specify the pseudorandom generator used.
