hey i'm trying to generate numbers from 1 to 3 in a way such that
number 1 has the probability 70% being generated
number 2 has the probability of 20% of being generated
number 3 has the probability of 10% of being generated
how do i do that?? can anyone please help.
Random r=new Random();
int i=1+r.nextInt(3);
this doesn't take into account the probabilities and generates the numbers in a random way..i need to generate the numbers according to their probabilites of being generated
Jump to Postgenerate a number between 1 and 10, then use an if statement to check which number was generated
gen < 7 gen = 1; gen < 9 gen = 2; gen == 9 gen = 3;
Jump to Post@sirlink99: good, but should line 5 of your pseudocode not read else instead of gen == 9?

It wouldn't matter, since the Random class return a number between 0(inclusive) and specified number (in this case 10)(exclusive). I would put it as gen == 9 just incase someone didn't know this(or programmed it wrong), and then place an else saying that "The generated number " + gen + " does not fit into any of the above ifs". This way the programmer would know something was wrong with the generated number before they realized that the probabilities were sqewed.
@sirlink99: OK I fully agree. But I just found it a little weird the way you wrote it. :)
hey thanks..i think this will work for me
