Question: Nathan makes 60% of his free-throw attempts. 60, 10) = 0.0196 Example 5: Binomial probability of at least x successes However, nowadays there are other online options to produce elegant graphing and. So begin with ‘y,’ as it allows you to finish the equation. You must have found many equation lists on the viewing window. The first and foremost important step is turning off stat plots, and it necessary completely.

If he shoots 12 free throws, what is the probability that he makes more than 10?Īnswer: Use the function 1 – binomialcdf(n, p, x):ġ – binomialcdf(12. Most secondary math classes require the use of a Ti-84 graphing calculator. How to Graph on Graphing Calculator TI-84. 60, 10) = 0.9804 Example 4: Binomial probability of more than x successes If he shoots 12 free throws, what is the probability that he makes at most 10?Īnswer: Use the function binomialcdf(n, p, x):īinomialcdf(12. 60, 9) = 0.9166 Example 3: Binomial probability of at most x successes If he shoots 12 free throws, what is the probability that he makes less than 10?Īnswer: Use the function binomialcdf(n, p, x-1):īinomialcdf(12. 60, 10) = 0.0639 Example 2: Binomial probability of less than x successes If he shoots 12 free throws, what is the probability that he makes exactly 10?Īnswer: Use the function binomialpdf(n, p, x):īinomialpdf(12.

Example 1: Binomial probability of exactly x successes The following examples illustrate how to use these functions to answer different questions. This will take you to a DISTR screen where you can then use binompdf() and binomcdf():

p = probability of success on a given trialīoth of these functions can be accessed on a TI-84 calculator by pressing 2nd and then pressing vars.

This tutorial explains how to use the following functions on a TI-84 calculator to find binomial probabilities:īinompdf(n, p, x) returns the probability associated with the binomial pdf.īinomcdf(n, p, x) returns the cumulative probability associated with the binomial cdf.

Results indicate that there was a statistically significant difference in problem-solving confidence scores between middle and high school students who used the Desmos graphing calculator as compared to students who used a TI-83 Plus graphing calculator, while controlling for student math achievement scores.The binomial distribution is one of the most commonly used distributions in all of statistics. Students in both groups took the assessment at the end of the 12-week period of learning and an Analysis of Covariance (ANCOVA) was used to test whether there was a significant difference in the scores of the Problem Solving Inventory (PSI). The students (N = 146) participating in this study were learning their respective mathematics material for an equivalent period of 12 weeks in order to determine whether students who used the Desmos calculator experienced a statistically significant difference in problem-solving confidence levels. The purpose of this quasi-experimental, non-equivalent control-group comparison study is to examine the impact the Desmos graphing calculator has on the problem-solving confidence of middle school and high school students as compared to students who use a TI-83 Plus graphing calculator while controlling for students’ math achievement scores. As technology in education continues to improve, research is necessary to assess the impact it is having on students’ confidence in the way students solve mathematics problems.
