Random number generator problems

My question is does the code below generate a random number properly as in the last 20 tries I got 500 000 5 times which does not reflect the 2% chance of getting it at all...

  public static int randInt(int min, int max) {

        // NOTE: Usually this should be a field rather than a method
        // variable so that it is not re-seeded every call.
        Random rand = new Random();

        // nextInt is normally exclusive of the top value,
        // so add 1 to make it inclusive
        int randomNum = rand.nextInt((max - min) + 1) + min;

        return randomNum;
    }

    public void prizegenerator(View v) {
        int fate = randInt(0,100);
        int reward=0;
        if (fate <= 30) {
            reward = 1000;
        }
        else if (fate <= 50) {
            reward = 2000;
        }
        else if (fate <= 80) {
            reward = 5000;
        }
        else if (fate <=90) {
            reward =  10000;
        }
        else if (fate <= 95) {
            reward = 50000;
        }
        else if (fate <= 97) {
            reward = 100000;
        }
        else if (fate <= 99) {
            reward = 500000;
        }
        else if (fate <= 100) {
            reward = 1000000;
        }
