RandomInteger

RandomInteger[{imin, imax}]
gives a pseudorandom integer in the range .

RandomInteger[imax]
gives a pseudorandom integer in the range .

pseudorandomly gives 0 or 1.

RandomInteger[range, n]
gives a list of n pseudorandom integers.

RandomInteger[range, {n1, n2, ...}]
gives an ××... array of pseudorandom integers.

DetailsDetails

• RandomInteger[{imin, imax}] chooses integers in the range with equal probability.
• gives 0 or 1 with 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.
