if lowBound and upBound are numbers, list
if lowBound and upBound are lists
geomCdf(p,upBound)for P(1≤X≤upBound)
⇒ number if upBound is a number, list if
upBound is a list
Computes a cumulative geometric
probability from lowBound to upBound with
the specified probability of success p.
For P(X ≤ upBound), set lowBound = 1.
geomPdf()
Catalog >
geomPdf(p,XVal) ⇒ number if XVal is a
number, list if XVal is a list
Computes a probability at XVal, the number
of the trial on which the first success occurs,
for the discrete geometric distribution with
the specified probability of success p.
Get Hub Menu
Get [promptString,] var[,statusVar]
Get [promptString,] func(arg1, ...argn)
[,statusVar]
Programming command: Retrieves a value
from a connected TI-Innovator™ Hub and
assigns the value to variable var.
The value must be requested:
• In advance, through a Send"READ..."
command.
—or—
• By embedding a "READ..." request as
the optional promptString argument.
This method lets you use a single
command to request the value and
retrieve it.
Example: Request the current value of the
hub's built-in light-level sensor. Use Get to
retrieve the value and assign it to variable
lightval.
Embed the READ request within the Get
command.
