How to Use GeoGebra as Binomial Distribution Calculator

The Probability Calculator in GeoGebra is easy to use. Here’s how you can use it compute probabilities from the binomial distribution.

GeoGebra Instruction 1

1.

Open Probability Calculator

under

View in

Menu.

2.

Make sure that you choose the Distribution tab at the top of the window.

3.

Select Binomial from the drop-down list. Insert the values for

n

and

p

from your problem.

4.

Choose Left-sided

, Interval

, Two tailed, or Right-sided

depending on your problem.

If you’re asked to compute the probability of getting exactly $k$ successes, you can find it in the table on the right-hand side.
If you’re asked to compute the probability of getting at least $k$ successes, choose Right-sided and enter the value of $k$ .
If you’re asked to compute the probability of getting at most $k$ successes, choose Left-sided and enter the value of $k$ .
If you’re asked to compute the probability that the number of successes is between $N$ and $M$ successes, including $N$ and $M$ , choose Interval and enter the values of $N$ and $M$ .
If you’re asked to compute the probability that the number of successes is not between $N$ and $M$ successes, including $N$ and $M$ , choose Two tailed and enter the values of $N - 1$ and $M + 1$ . Alternatively, you can compute the probability in the item above, and then take that probability and subtract it from 1.
