RandomInteger

RandomInteger[{imin, imax}]
gives a pseudorandom integer in the range {i_(min),…,i_(max)}.
RandomInteger[imax]
gives a pseudorandom integer in the range {0,…,i_(max)}.
RandomInteger[]
pseudorandomly gives 0 or 1.
RandomInteger[range, n]
gives a list of n pseudorandom integers.
RandomInteger[range, {n1, n2, ...}]
gives an n_1⨯n_2⨯… array of pseudorandom integers.
RandomInteger[dist, ...]
samples from the symbolic discrete distribution dist.
  • RandomInteger[{imin, imax}] chooses integers in the range {i_(min),…,i_(max)} with equal probability.
  • RandomInteger gives a different sequence of pseudorandom integers 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.
