Hello Leigh thank youfor the video, on a small project I am working on I need to know how to loop randInt. I know you can do randInt(1, 2, 5) and 5 would be the ammount of times it would choose a random number. What I need is for the calculator to do randint(1, 2) 5 sperate times. So I now manually have to do, randint(1, 2) randint(1, 2) randint(1, 2) randint(1, 2) randint(1, 2). Of course with only 5 numbers it would be easy but is there any way to do this so that the calculator does it 5 separate times? Thank you in advance!

Random number generation on the TI-NSpire. Be sure to have students seed their calculators with different numbers.
TI-NSpire Quick Tip #41

All calculators use a program internally to generate a list of "random" numbers. If all students in a class generated the list of random numbers, they would get the exact same list! It is not very random if I can predict what number will show up on your calculator, because it showed up on my calculator, too!
To get students to have different lists of random numbers, they need to "seed" their calculator with a number that is different than the other students in the class. I usually suggest a phone number or locker combination. With everyone using a different starting "seed" number, the program will generate different lists of "random" numbers.
The tip of "seeding" the calculator is more important for the teacher who is teaching concepts of randomness in their classroom.
