Probability

nPr

Calculates the number of possible permutations

Errors

ARGUMENT

— A function does not have the correct number

of arguments.

DIVIDE BY 0

—

You attempted to divide by 0.

In statistics, n=1.

DOMAIN

— You specified an argument to a function outside

the valid range. For example:

For x

‡

: x = 0 or y < 0 and x not an odd integer.

For yx: y and x = 0; y < 0 and x not an integer.

For

‡

x: x < 0.

For LOG or LN: x

For TAN: x = 90

, -90

, 270

, -270

, 450

, etc.

For SIN

1 or COS

1: x > 1.

For nCr or nPr: n or r are not integers

‚

For x!: x is not an integer between 0 and 69.

EQUATION LENGTH ERROR

— An entry exceeds the digit

limits (88 for Entry Line and 47 for Stat or Constant Entry
lines); for example, combining an entry with a constant that
exceeds the limit.

FRQ DOMAIN

—

FRQ

value (in

1-VAR

stats) < 0 or >99, or

not an integer.

OVERFLOW

—

‚

10, where

is an angle in a trig,

hyperbolic, or R

STAT

—

Pressing

SYNTAX

— The command contains a syntax error: entering

more than 23 pending operations or 8 pending values; or
having misplaced functions, arguments, parentheses, or
commas.

Battery Replacement
