How to calculate 1) binomial coefficients and 2) binomial distribution on a Casio fx-9860G calculator?

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.

I would like to highlight that the Casio fx-9860G calculator is a powerful tool for performing calculations related to binomial coefficients and binomial distribution. These calculations are essential in many areas of science, including statistics, probability, and genetics.

To calculate binomial coefficients on the Casio fx-9860G calculator, you can use the "nCr" function. This function allows you to calculate the number of ways to choose a subset of r objects from a set of n objects. To use this function, you can first input the value of n, press the "shift" button, and then press the "nCr" button. Next, input the value of r and press the "=" button to get the result.

To calculate binomial distribution, you can use the "binompdf" function. This function allows you to calculate the probability of getting a specific number of successes in a certain number of trials, given a probability of success. To use this function, you can input the number of trials, probability of success, and the number of successes you want to calculate the probability for. Then press the "shift" button, followed by the "binompdf" button, and then the "=" button to get the result.

Overall, the Casio fx-9860G calculator is a reliable and efficient tool for performing calculations related to binomial coefficients and binomial distribution. It can greatly aid scientists in their research and analysis, making it a valuable asset in the scientific community.
