Casio fx-9860G - calculating binomial coefficients and binomial distribution

Click For Summary

Discussion Overview

The discussion focuses on how to calculate binomial coefficients and binomial distribution using the Casio fx-9860G calculator. It includes practical steps for using the calculator's functions and features related to statistical calculations.

Discussion Character

  • Technical explanation

Main Points Raised

  • One participant inquires about the methods for calculating binomial coefficients and binomial distribution on the Casio fx-9860G calculator.
  • Another participant suggests using an "NCR button," which is later challenged by a different participant who states that such a button does not exist on the calculator.
  • A participant provides detailed steps for calculating binomial coefficients using the "C" function found in the CATALOG and describes the process for calculating binomial distribution through the STAT menu.
  • Additional information is shared via a link to the user manual for the calculator, expressing frustration about the lack of this resource at the time of purchase.

Areas of Agreement / Disagreement

There is no consensus on the existence of an "NCR button," as one participant asserts its absence while another suggests its use. The discussion includes both clarification of calculator functions and personal experiences without resolving the initial inquiry.

Contextual Notes

Participants reference specific functions and steps that may depend on the version of the calculator or user familiarity with its interface. There may be limitations in the clarity of instructions provided.

How to calculate 1) binomial coefficients and 2) binomial distribution on a Casio fx-9860G calculator?
 
Physics news on Phys.org
try the NCR button
 
There is nothing like an "nCr button" on Casio fx-9860G, sorry. In any case, I have already found the answer, thank you.

For posterity:

To calculate binomial coefficients, you need to find the "C" function (the fat-looking C letter) under the CATALOG in the C's and type the n and r values on either side of the C as it appears on screen (e.g. 4C2).

To calculate binomial distribution, 1) go to "Menu", 2) select "STAT", 3) select "DIST" (under F5), 4) select "BINM" (under F5), 5) select "Bpd", 6) change inputting the DATA from "List" to "Variable" (F2), 7) enter your data and 8) select "Execute."
 
One more thing for posterity:

Why wasn't this included in the package when I bought the calculator? In any case, I wish someone had shown me this link a year ago.
