Stupid calculator question

[vetteguy]

A co-worker is taking a class where she has to use a TI-83 to do some basic statisitcs. It's been so long since I've done anything like this I honestly can't remember, and I never had an 83 so I'm not much help. Anyway, she's supposed to use the RandInt() function to simulate rolling 2 dice 1000 times, and plot the probablity of the numbers. I figured out the RandInt() on the thing, but I'm not sure how to do it for 2 dice 1000 times. Any ideas? Just as an example, I used RandInt(1,6,2) to simulate rolling 2 dice once. Is that accurate? Like I said, this was back in high school for me, so I'm a little rusty. Thanks!

Thanks...I've been to the manual, the problem is that it's quite large. I was wondering if anyone knew off the top of their head how to do the problem I described.

randInt ( lower, upper, numtrials)

But in my case, she needs to simulate 2 dice at the same time. That's why I'm unsure of how to get randint to do that...I can say RandInt(1,6,2) but she needs it repeated 1000 times. Is there some easy way to output that to a list?

i'm just guessing here , but could you do something like : randInt(lower,upper, numtrials) + randInt(lower, upper, numtrials)

I don't know, that's why I'm asking.
