Casio FX-87DE CW
Scientific calculator with FULL DOT display and 580 functions
The innovative operation and menu-based navigation simplify the use of the calculator for students. Shortcuts and key combinations are largely dispensed with. To this end, the functions have been expanded to include the "Maths Box" (for dice and coin tossing experiments). The maths box can be used to simulate dice and coin tossing experiments. The relative frequencies of the sums can be listed.
