RandomSample
RandomSample[{e1, e2, ...}, n]
gives a pseudorandom sample of n of the 
.
RandomSample[{w1, w2, ...}->{e1, e2, ...}, n]
gives a pseudorandom sample of n of the 
chosen using weights 
.
RandomSample[{e1, e2, ...}]
gives a pseudorandom permutation of the 
.
Details
- RandomSample[{e1, e2, ...}, n] never samples any of the
more than once. - RandomSample[{e1, e2, ...}, n] samples each of the
with equal probability. - RandomSample gives a different sequence of pseudorandom choices whenever you run Mathematica. You can start with a particular seed using SeedRandom.
- A Method option to SeedRandom can be given to specify the pseudorandom generator used.
