geometric distribution with the specified probability of
success p.

A:Get(
GetCalc(variable
[,portflag])
Gets contents of variable on another TI-84 Plus and stores it
to variable on the receiving TI-84 Plus. By default, the TI-84
Plus uses the USB port if it is connected. If the USB cable
is not connected, it uses the I/O port.
portflag=0 use USB port if connected;
portflag=1 use USB port;
portflag=2 use I/O port.

getTime Returns a list giving the time according to the current value
of the clock. The list is in {hour,minute,second} format. The
time is returned in the 24 hour format.
