randBin()

⇒
n p expression
randBin( , )
⇒
n p #Trials
randBin( , , )
n p
returns a random real number from a specified
randBin( , )
Binomial distribution.
n p #Trials returns a list containing #Trials random real
randBin( , , )
numbers from a specified Binomial distribution.

randInt()

lowBound upBound
randInt( ,
lowBound upBound
randInt( ,
lowBound upBound
randInt( ,
range specified by lowBound and upBound integer bounds.
lowBound upBound
randInt( ,
#Trials random integers within the specified range.

randMat()

numRows numColumns
randMat( ,
Returns a matrix of integers between -9 and 9 of the specified
dimension.
Both arguments must simplify to integers.

randNorm()

⇒
m s
expression
randNorm( , )
m s
#Trials
randNorm( , ,
m s
returns a decimal number from the specified
randNorm( , )
normal distribution. It could be any real number but will be heavily
concentrated in the interval [
m s #Trials
randNorm( , ,
numbers from the specified normal distribution.

randPoly()

⇒
Var Order
randPoly( , )
Returns a polynomial in Var of the specified Order. The coefficients
are random integers in the range
coefficient will not be zero.
Order must be 0–99.

randSamp()

List #Trials
randSamp( , [,
Returns a list containing a random sample of #Trials trials from List
with an option for sample replacement (noRepl=0), or no sample
replacement (noRepl=1). The default is with sample replacement.
