(make-random-state &optional state)
Function: Make a random state object. The optional STATE argument specifies a seed for deterministic pseudo-random number generation. As per the Common Lisp standard, - If STATE is NIL or not supplied or is NIL, return a copy of the default *RANDOM-STATE*. - If STATE is a random state, return a copy of it. - If STATE is T, return a randomly initialized state (using operating-system provided randomness source where available, otherwise a poor substitute based on internal time and pid) See SB-EXT:SEED-RANDOM-STATE for a SBCL extension to this functionality.

(alexandria.0.dev:random-elt sequence &key (start 0) end)
Function: Returns a random element from SEQUENCE bounded by START and END. Signals an error if the SEQUENCE is not a proper sequence.
  
(alexandria.0.dev:gaussian-random &optional min max)
Function: Returns two gaussian random double floats as the primary and secondary value, optionally constrained by MIN and MAX. Gaussian random numbers form a standard normal distribution around 0.0d0.
