Description
rand83(
random number
Generates and displays a LIST containing one or more random numbers
> 0 and < 1 for a specified number of trials (NUMTRIALS). Returns
random values (0,1). If NUMTRIALS is not provided, a single random
number between 0 and 1 is returned.
nPr(
permutations
(number of permutations) returns a LIST containing the permutations
based on the input arguments, EXPR1 and EXPR2,
which can be integers,
symbolic expression, or lists of these two data types.
nCr(
combinations
(number of combinations) returns a LIST containing the combinations
based on the input arguments, EXPR1 and EXPR2, which can be
integers, symbolic expression, or lists of these two data types.
!
factorial
(factorial) returns a LIST containing the factorial of the expression
(EXPR) . Expressions include integers, symbolic expression, or list of
these two data types.
randInt(
random integer
(random integer) generates and displays a LIST of random integers
within a range specified by LOW and UP integer bounds.
.randNorm(
random normal
distribution
Given the mean (m ), standard deviation (s ), and the number of trials
(NUMTRIALS),
.randNorm( returns a LIST containing the decimal
numbers from the specific normal distribution.
randBin(
random binomial
distribution
Generates and displays a LIST containing random real numbers from a
specified binomial distribution with the probability of success (P) and
with a specified number of trials (N).
randSamp(
random sample
Returns a LIST containing a random sample of the size you CHOOSE
from a LIST with an option for sample replacement (NOREP=0), or no
sample replacement (NOREP=1). The default is with sample replacement.
rand(
random number
With no parameter, rand( returns a LIST element containing the next
random integer between 0 and 1 in the sequence. When INT is positive,
rand( returns a LIST element containing a random integer in the interval
[1, n].
When INT is negative,
rand( returns a LIST element containing a random
integer in the interval [ën,ë1].
RandSeed
random seed
If Integer Seed = 0, sets the seeds to the factory defaults for the
random-number generator. If
Integer Seed π 0, it is used to generate two
seeds, which are stored in system variables
seed1 and seed2.
