Using The TI-83/84 Plus Chapter 5: Binomial Probabilities In the book we used a complicated formula or Table 1 to get binomial probabilities. We added these probabilities together to get cumulative binomial probabilities. The video and the instructions below demonstrate how to complete these tasks with the TI 83/84 calculators. • Binomial Probabilities look like P (x = 4 | n = 10, p = 0.7). • Cumulative Binomial Probabilities look like P (x ≤ 4 | n = 10, p = 0.7) where x = the number of successes, n = the number of trials, p = probability of a success on a single trial.

• This video demonstrates both types of probabilities. • Brief Directions:

– Using the binompdf(n,p,x) function. (Binomial Probability Density Function) 1. Hit 2nd button then the VARS button to access the DISTR (distributions) menu. 2. Highlight the DISTR option and scroll down (using the down arrow ↓ button) to highlight the binompdf option then hit ENTER . 3. Put a value in for n, then a comma (it has its own

,

button), then the value for p, a

comma, the value for x, and finally the right parentheses ) button to close the function. Hit ENTER . 4. Example P (x = 4 | n = 10, p = .7) binompdf(10, .7, 4) = 0.0368 – Using the binomcdf(n,p,x) function. (Binomial Cumulative Density Function) 1. Same as above only you highlight and select the binomcdf option then hit ENTER . 2. Example P (x ≤ 4 | n = 10, p = .7) binomcdf(10, .7, 4) = 0.0473...
