Seed Sets the seed value on which the random functions operate.

By specifying the same seed value on two or more calculators,

you ensure that the same random numbers appear on each

calculator when the random functions are executed.

RANDSEED(value)

Density

Normal Normal probability density function. Computes the

probability density at value x, given the mean, and

standard deviation, of a normal distribution. If only one

argument is supplied, it is taken as x, and the assumption is

that =0 and =1.

NORMALD([,,]x)

Example:

NORMALD(0.5) and NORMALD(0,1,0.5) both return

0.352065326764.

T Student’s t probability density function. Computes the

probability density of the Student's t-distribution at x, given n

degrees of freedom.

STUDENT(n,x)

Example:

STUDENT(3,5.2) returns 0.00366574413491.

probability density function. Computes the probability

density of the distribution at x, given n degrees of freedom.

CHISQUARE(n,x)

Example:

CHISQUARE(2,3.2) returns 0.100948258997.

F Fisher (or Fisher–Snedecor) probability density function.

Computes the probability density at the value x, given

numerator n and denominator d degrees of freedom.

FISHER(n,d,x)

Example:

FISHER(5,5,2) returns 0.158080231095.
