Generating Random Numbers (Need help ASAP!)

Working on a math problem.

• First, I need to generate a random integer from 1 to 6. I need to keep doing this until I get the number 3. I need to record how many numbers had to be generated.
• Second, I need to generate random integers from 1 to 6 until I have picked every number once. Again, I need to know how many numbers were generated.

I need to do each situation a certain number of times (which is up to me) to get an average of how many numbers had to be generated in order to meet the condition.

Being the overachiever that I am, I'd like to generate an absurd number of trials. So I want to do the first situation a huge number of times and then get the average. Same for situation 2. Is there any way I could use my computer to do this? My Q6600 is on Windows and my 2GHz Core Duo laptop runs Ubuntu.

Maybe I should explain more. The teacher expects us to either use a random number chart in our math books or use our calculator to generate random numbers. He also expects us to do anywhere from 5-10 trials and then get an average from that. I can do that no prob.

But being me, I thought, "Wouldn't you get a much more accurate average if you had more trials? Say 1000, or 1,000,000?" Doing it with the chart or manually on the calc would take forever. Writing a program on the calc would be faster. But then I thought, wouldn't a computer be really fast? So basically, I'm trying to create as many trials as possible, even though it's complete overkill. I don't mean to ask anyone to do everything for me.

Whoa. I get the sense that this is the tip of the iceburg of a really big and complex issue...
I take it that a calculator (and a computer) will generate psudo-random numbers then. If so then I would think that that's ok.

 

Generating Random Numbers (Need help ASAP!)

The outcome of rolling a physical dice depends upon environmental variables in your physical surroundings. Random algorithms, that generate pseudo-random numbers, do not take any physical properties into play. The outcomes of each will differ.

You can do this easily in basic.

create a counter variable and set it to zero
Do a while loop until the terminating condition is met (eg. random number = 3)
Increment the counter
Generate a random number between 1 and 6
If the condition is met, break out of the loop.
If not, let the loop run again.
The counter will hold the number of attempts.

The second one is a little more complex as you will have to store which numbers have been "hit" and re-roll if you hit a number twice.

Since there are no requirements on how many times you have to do this to create an average, it may quicker to just roll dice.

That is, of course, up you you and we wil lend a hand if need be.
We will not however, code the whole assignment for you.
So chop chop grasshopper, be an overachiever and get to coding !!! *Wink
