  6. Re: Dice Rolling Probability - How Do I Start It Off?

    Okay well here's what I have so far. I'm not sure if even this is correct. How do I display the number of times it matches for each sum?


    import java.util.Random;
    import java.util.Scanner;...
  7. Re: Dice Rolling Probability - How Do I Start It Off?

    -Calculate the probability of each...
  9. Re: Dice Rolling Probability - How Do I Start It Off?

    For example, since I'm doing a 2-sided dice...

    It's supposed to represent all the possible sums I could get from the dice. So the lowest possible number would be 2 and the highest would be 4.

    If the sum on the dice is equal to the sum, then it...

    Re: [Help] For Loops - Number Predicting Program

    Okay thank you. That'll be a start. I kind of have an idea of how to do this now. Why does this belong in the Java Theory board? Because it's Java lol? Or because I don't actually have a code to...

  15. Re: Reading Text Files Assignment [Scanner Method]

    I meant like how can I make it so that each line can be read one at a time to determine if it is equal to BB, BG, GB, or GG. I don't know how to do that.

    And that's another problem I have. I don't...
