First Steps with TI-Nspire™

Tutorial 2: The Calculator Application

The Calculator Menu
Press b and look at the extensive system of menus and
submenus available in the Calculator application. If you used
the TI-83 or TI-84 graphical calculators you will be familiar
with many of these expressions.
More details can be found in the Getting Started Guide.
This screen shows a simulation of 100 throws of two dice and
uses commands from the Probability and Statistics
sub-menus.
To enter randInt you can either press
b542	Lists of random integers
to navigate through the menus or you can spell it out, letter
by letter.

You will find the mean command by pressing b633.

Notice that the expression d1+d2 produces a list of 100 sums of the corresponding

values from d1 and d2 i.e. 100 totals when 2 dice are thrown

Statistical Distribution Tables

A useful feature of the TI-Nspire is the ability to work with probability distributions such as the Binomial, Poisson and Normal distributions. These can be found by pressing b65.

These provide wizards which enable you to calculate the probability for a given distribution instead of looking up the value in a table.
